Abstract: A buckle includes a male member and a female member. The male member is provided with a base, a pair of legs and an engaging portion provided on a distal ends of the legs. The female member is provided with an insertion port, a guide that elastically deforms the distal end of each of the legs inserted through the insertion port in a direction in which the distal ends come closer to each other and a pair of engaged portions formed on both sides of a remote side of the guide. Each of the engaged portions displaces each of the engaging portions in the direction in which the engaging portions get apart with each other and is provided by a concave that has an abutment wall on a rear portion in the releasing direction to be abutted by each of engaging portions. Each of the abutment walls is formed as a slant surface that inclines in the direction in which the abutment walls come closer to each other toward the releasing direction of the male member.

Abstract: A connecting device which has an excellent appearance, produces no frictional sound between a connecting device main body such as a swivel hook main body and a belt attaching member and can be assembled easily and securely. The connecting device includes a neck portion standing from a proximal portion of a main body of the connecting device and an engagement head which is expanded in an outward direction form a center of an axis line such that a diameter thereof can be reduced, the engagement head being provided at a front end of the neck portion. A belt attaching member is connected to the main body rotatably around the neck portion. A through hole which the engagement head can be engaged with by insertion is formed in part of the belt attaching member. In the through hole, a small-diameter hole portion having a smaller diameter than the diameter of the engagement head and a large-diameter hole portion having a large diameter than the diameter of the engagement head are connected via a stepped portion.

Abstract: To connect a belt connecting member (4) of a first member (1) with a snap hook (5) of a second member (2), a neck portion (21) having a circular cross section is provided so as to project from a connecting portion of the snap hook (5), a bulging portion (22) is provided on a tip end of the neck portion (21) so as to radially bulge to define an engaging portion (23), a fitting hole (13) is provided on a connecting portion of the belt connecting member (4) with an engaged portion (15) that is engageable with the bulging portion (22), the engaged portion (15) and the engaging portion (23) are formed in an oval shape having a long axis (L, L?) in a flush plane of the belt connecting member (4) and the snap hook (5) and a short axis (S, S?) in orthogonal planes of the belt connecting member (4) and the snap hook (5), and the engaging force can be largest when the snap hook (5) is in its most general state in use where the belt connecting member (4) and the snap hook (5) are orthogonal.

Abstract: A buckle (10) including a plug (30) and a socket (20) is provided with a posture-adjuster that adjusts relative postures of the plug (30) and the socket (20) in a direction that leads a longitudinal axis (A2) of the plug (30) and a longitudinal axis (A1) of the socket (20) to be parallel when the plug (30) is relatively moved in a direction toward inside of the socket (20) from an insertion slot (21) thereof. The posture-adjuster has a guide path (24) that is provided to the socket (20) and has a width that becomes wider as being closer to the front end side thereof as well as a step portion (36) as a guided member that is provided to the plug (30) and guided by the guide path (24).

Abstract: A buckle which is an insertion type, wherein looseness between a buckle main body and an insertion body is eliminated and generation of impact sound or vibration sound is prevented, and in a resin buckle including the buckle main body formed of a housing and the insertion body having insertion leg portions on both sides, a concave guide groove is provided in a longitudinal direction of a center of an inner face of each of an upper face plate and a lower face plate of the housing of the buckle main body, while a guide lever which can be inserted into the guide groove provided in the housing is provided in a protruded form in a center of a proximal lever of the insertion body. A sliding contact portion which is elevated to make pressure contact with an opposing face is provided in part of the guide groove or the guide lever, or both the guide groove and the guide lever.

Abstract: A sheet attaching instrument (10) that includes an instrument body (11) and an attachment member (12), in which at least one engaging hole (50) is provided with a fall-stop (58) that can hold an attachment projection (30) in an area between an inserting section (51) and a holding section (52), and at least one peripheral edge of a pair of lateral side areas extending from the inserting section (51) to the holding section (52) through the fall-stop (58) is provided with a bridge (54) of which middle section is elastically deformable.

Abstract: A buckle includes a socket (10), a plug (20) of which tip end part can be inserted into and released from the socket by pressing both sides of the socket by a manual operation. The plug has a base (21) located on a base end of the plug, a pair of lock arms (22) extending to the tip end of the plug from the base, an engaging part (24) provided on the intermediary of the lock arm and engageable with the inside of the socket, a pressing part (25) provided on the intermediary of the lock arm and pressed by the manual operation, and a bridge (30) for connecting the intermediaries of the lock arms.

Abstract: A buckle, which comprises a female body and a male body, which may be inserted each other and prevents rocking in right and left directions and clattering of the female body and the male body at the time, is provided. A buckle comprising a female body formed with a flat housing and a male body having a pair of right and left flexible insertion legs, wherein when the female body and the male body are inserted to engage, the butting surfaces between the female body and the male body on a plane, that is, butting portions are formed with horizontal straight portions on both sides of the butting portions as well as a concave portion at the center in female body and a convex portion in the male body, or a convex portion in the female body and a concave portion in the male body continuously formed, so as to join the female body to the male body in the condition closely in contact.
