Abstract: A side release buckle includes: a plug; and a socket, the plug including: a base; a pair of legs; and engaging portions, the socket including: a body; an insertion opening; a housing space; engaged portions; and a pair of guide surfaces. The guide surfaces, which are formed on an inner surface of the housing space and extend in an insertion direction of the legs while being opposed to each other, each include: a squeezing portion formed continuously with corresponding one of the engaged portions; and a guiding portion formed between the squeezing portion and the insertion opening. An interval between the guiding portions-near the engaged portions is wider than an interval between the squeezing portions near the engaged portions. An inclination angle of each guiding portion to an insertion direction of the plug is smaller than an inclination angle of each of the squeezing portion to the insertion direction.

Abstract: A buckle includes a male member and a female member. The male member includes: a base; a pair of legs that project from the base; engaging portions that are provided on the legs to be engageable with the female member; and a linking body that links the pair of legs. The linking body includes a curved portion that is curved such that the middle thereof is closest to the base. A pair of projecting portions that are substantially parallel with an insertion direction of the male member extend from the base to be disposed outside the curved portion such that the curved portion is interposed therebetween. With this arrangement, the linking body for linking the pair of legs can be disposed with less possibility that other objects are caught in a space in the male member and without increasing a length dimension in the insertion direction more than necessary. The male member can be stably held relative to the female member against a torsion force.

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: 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 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.

The linking body includes a curved portion that is curved such that the middle thereof is closest to the base. A pair of projecting portions that are substantially parallel with an insertion direction of the male member extend from the base to be disposed outside the curved portion such that the curved portion is interposed therebetween.
