Abstract: A bus bar includes a body having at least one bent portion and a plate-shaped or bar-like terminal located on at least one end of the body and formed of a material identical with a material of the body integrally with the body in a seamless manner. The terminal is formed by pressurizing the end of the body thereby to be plate-shaped or bar-like and having a higher hardness than the bent portion. The body is solid and linear in shape. The terminal is formed so that its profile has a required predetermined size by adjusting an applied pressure value.

Abstract: This torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body comprises a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.

Abstract: Preventing a checker from becoming waste even after fulfillment of a detecting function and stably maintaining a retainer in a locking state. A pipe connector includes a connector body (1), a retainer (2) preventing a pipe from pulled from the connector body (1) and a checker (3) detecting normal insertion of the pipe. The checker (3) is formed with front legs (37). When the pipe (P) has been inserted into a normal position, the front legs (37) are spread by a flange (10) of the pipe (P) with the result that the checker (3) is released from the lock to the connector body (1). Consequently, the checker (3) is movable from a preliminary holding position to a detection position by pressing a cover (34). Locking legs (26) are spread when a release operation portion (28) of the retainer (2) has been pressed, so that the pipe (P) is allowed to be pulled from the connector (1).

Abstract: A hose clamp for preventing a leak during tightening of a hose includes a clamp body with a strip-shaped leaf spring having an annular shape, and a pair of operation pieces. The clamp body maintained in a diameter expansion state by a locking claw of the operation piece engaged with an engagement concavity of the operation piece of the clamp body. The locking claw is released by bringing the operation piece on one side close to the operation piece on the other side and moving the operation piece on one side with respect to the operation piece on the other side in the opposing direction in an axial direction of the clamp body, reducing the clamp body in diameter. A leak prevention piece presses a hose during tightening of the hose at an end portion of the operation piece on the other side of the clamp body.

Abstract: A connector has a pivot shaft extending axially between a pair of flanges of a connector body. The retainer includes a bearing portion at one end, with an expandable insertion slot engageable with the pivot shaft such that the retainer pivots about the pivot shaft. The retainer has a temporary engagement position where a pipe can be inserted and removed and a regular engagement position where a bulge portion of the pipe is engaged preventing the pipe from being removed. A stopper claw formed on an opening edge of the insertion slot contacts with a contact surface, preventing the connector body from pivoting beyond the temporary engagement position. This prevents a condition where the retainer further pivots past the temporary engagement position which can cause the insertion slot to expand and the retainer separating from the pivot shaft.

Abstract: The pinching operation is facilitated. A hose clamp (H1) is formed by bending a strip-like plate material (1) into a ring-like configuration, and includes a first end portion (5) having a first pinching operation surface (9), and a second end portion (6) having a second pinching operation surface (15). A through-hole (7) is open near the center in the longitudinal direction of the first pinching operation surface (9). At the time of bending into ring-like configuration, expansion regions (19) arranged at both side portions in the width direction of the second pinching operation surface (15) are folded at folding edges (20) with respect to a proximal region (18), whereby the second pinching operation surface (15) is narrowed in the width direction and can enter the through-hole (7). After bending into ring-like configuration, the expansion regions (19) are unfolded at the folding edges (20) and regain a widened state.

Abstract: A hose clamp includes a body elastically deformable between a closed-diameter state and an opened-diameter state, a first grip piece, a second grip piece, a lock portion located on either the first or second grip piece, a lock receiving portion located on the other grip piece side and elastically displaced together with the lock portion when the grip pieces are caused to come close to each other, thereby being locked to the lock portion by a subsequent return operation. The lock receiving portion holds the body in the opened-diameter state when in a locked state, and a restricting portion is capable of restricting displacement of both grip pieces in reverse of the direction of the elastic displacement. Either the first or second grip piece formed with the restricting portion has a distal end located lower than a distal end of the other grip piece when the body is in the closed-diameter state.

Abstract: A hose clamp capable of preventing generation of a leak flow path during tightening of a hose is provided. A hose clamp (10) includes a clamp body (12) formed by bending a strip-shaped leaf spring material into an annular shape, and a pair of operation pieces (13 and 21). The clamp body (12) is maintained in a diameter expansion state by making a locking claw (14) on a side of the operation piece (13) on one side be engaged with an engagement concavity (22) on a side of the operation piece (21) on the other side of the clamp body (12). The engagement of the locking claw (14) with the engagement concavity (22) is released by bringing the operation piece (13) on one side close to the operation piece (21) on the other side and moving the operation piece (13) on one side with respect to the operation piece (21) on the other side in the opposing direction in an axial direction of the clamp body (12), whereby the clamp body (12) is reduced in diameter from the diameter expansion state.

Abstract: A hose clamp for preventing a leak during tightening of a hose includes a clamp body of a strip-shaped leaf spring material with an annular shape, and a pair of operation pieces. The clamp body maintained in a diameter expansion state by a locking claw of the operation piece engaged with an engagement concavity of the other operation piece. The engagement released by bringing the operation piece close to the other operation piece and moving the operation piece in the opposing direction in an axial direction of the clamp body, whereby reducing the clamp body diameter. An expansion restricting piece restricts divergence of both the operation pieces in opposite directions in the axial direction of the clamp body. Further, a tilt prevention section which prevents the clamp body from being obliquely assembled to a hose during tightening of the hose is provided.

Abstract: An inlet hole capable of inserting a pipe thereinto is formed in a pipe joint body along an axis. Retainer attaching holes for attaching with a retainer that prevents detachment of the pipe are formed in a side surface of the pipe joint body to extend therethrough. These retainer attaching holes are configured symmetrically with respect to an X axis passing through a center of the inlet hole as a symmetrical axis. Thus, a circumference of the inlet hole opens symmetrically, so that the heat shrinkage condition after molding is equalized in the circumferential direction. Accordingly, it is not necessary to process a molding pin for the inlet hole with imbalance of heat shrinkage amount in mind, so that the molding pin becomes easy to process. In addition, the retainer can selectively utilize the retainer attaching holes at two positions, so that selective use depending on installation environment can be achieved.

Abstract: A hose clamp includes a first grip piece (6) on one end of a body (2) and a second grip piece (7) on the other end. A locking portion (L1) extends from the first grip piece (6) toward the second grip piece (7), and a restricting portion (R1) is projected from the root of the second grip piece (7). When the grip pieces (6, 7) are moved closer to each other to transfer the body (2) from a closed-diameter state to an opened-diameter state, the locking portion (L1) abuts with the top of the restricting portion (R1), and the upward movement of the second grip piece (7) in association with the operation of the grip pieces is restricted. During the operation, the locking portion (L1) is in slide-contact with a guide surface (15) formed on the top of the restricting portion (R1) and, accordingly, the locking portion (L1) is guided to a receiving portion (A1) of the second grip piece (7). Thus, the engagement operation between the locking portion (L1) and the receiving portion (A1) is guided.
