Abstract: Fretting wear in a pipe connector is avoided in advance. In a connector body (1), there is provided a gate member (29) having spring portions (33) that allow a pipe (P) to be inserted up to a regular depth while maintaining a contact state with the pipe (P). When a retainer (37) is pushed in with the pipe (P) being inserted to the connector body (1) up to the regular depth, locking legs (45) of the retainer (37) are locked to a bulge portion (6) of the pipe (P) and each locking leg (45) enters between the pipe (P) and the spring portion (33) and elastically displaces the spring portion (33) in a direction away from the pipe (P), thereby eliminating the contact state.

Abstract: A connector includes a connector body having a hollow channel, and a retainer configured to prevent a pipe inserted into the hollow channel from being removed using a stopper piece. The retainer body lies along the outer peripheral surface of the retainer attachment portion. A bearing allows the retainer body to rotate from a temporary locking position to a main locking position. A detection piece passes through a detection hole and projects into the hollow channel when located in the temporary locked position, so as to be pushed in an axial direction by a bulge of the pipe. An inclined surface of the detection piece inclines with respect to the axial direction such that a pushing force can be converted to a radially outward force. A first energy conversion mechanism serves to convert the energy converted by the inclined surface to the rotational energy in the locking direction.

Abstract: A purpose is to render a gripping operation of grip tabs more stable. A hose clamp includes a clamp body formed by bending a plate spring into an annular shape while two ends of the plate spring are caused to cross each other on a circumferential plane and grip tabs formed to be raised radially outward from both ends of the clamp body, respectively. An expanded-diameter state of the clamp body is retained when a locking claw is locked by a catch. The clamp body is released from the expanded-diameter state when a gripping operation is further carried out in this state. The second grip tab has a distal end formed to be wider than a distal end of the first grip tab. The distal ends of the grip tabs are bent in respective directions in which the distal ends depart from each other with respect to a thicknesswise direction, thereby serving as bent portions for the gripping operation, respectively.

Abstract: A purpose is to increase a clamping force without increase in a plate thickness. A wide region (X1) is formed at one of lengthwise sides to be relatively wider and has portions bifurcated by an opening (2). A narrow region (X2) is formed at the other lengthwise side to be relatively narrower and has a portion passed between the bifurcated portions. Both widthwise side edges of the wide region (X1) are formed with respective flanges (6) by bending and a bead (7) is formed on a widthwise middle of the narrow region (X2). The flanges (6) and the bead (7) are set so that a change in a section modulus is substantially symmetric about a Y axis that is a lengthwise central axis of the hose clamp.

Abstract: A torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body includes 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: A hose clamp includes a clamp body formed by bending a plate spring into an annular shape while two ends of the plate spring are caused to cross, grip tabs formed to be raised radially outward from both ends of the clamp body, respectively and an expanded-diameter state retainer formed integrally on the clamp body or the tabs and capable of retaining an expanded-diameter state of the clamp body and releasing the clamp body from the expanded-diameter state by relative movement of both tabs in an axial direction of the clamp body with a gripping operation applied to both tabs. The tabs have respective distal ends, one of which has a larger width than the other. The distal ends are bent circumferentially outward into bent portions spaced from each other. The bent portions are insertable into positioning recesses formed in opposite surfaces of a gripping tool, respectively.

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 pipe connector includes a connector body, a retainer having a pair of locking legs and a release operation portion, and a checker. The connector body has an insertion hole into which a pipe is insertable. The locking legs are deformable to be spread and closed and are moved into the insertion hole. The release operation portion being operable to displace the locking legs in a direction such that the pipe is releasable from a retained state. The checker is formed separately from the retainer and lockable to the connector body and releasable from a locked state to be movable to a detection position when the pipe is inserted into the insertion hole. The checker is formed with pressing pieces located rearward relative to the locking legs when the checker assumes the detection position, to thereby prevent the locking legs from being flexed rearward.

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.
