The part 2 is =1. When the n part n of the female part i is fully pressed, it is formed in the form of the engaging convex part i 〇g of the female part in the true grooving recess 21e. Specifically, In the illustrated example, each of the f 21b' formed in the shaft portion 21 of the male part 2 is formed with a fastening recess 21e at each joint portion of the rib 21b and the head portion 2, and In the longitudinal direction of the rib hunger, the position of the middle 曰 ' is formed into a temporary snap-fit recess 2u. Then, in this example, the protruding dimension of the core portion 21 a from the uranium is set to be larger than that from the aforementioned insertion hole The 318745 13 1303292 inch of the entrance of the divergent hole portion 1〇c of the 10a to the engaging convex portion 10(10) is also slightly larger. By this, the embodiment is made by making the shaft portion 21 of the male part 2 The rib 21b of the part 2 is inserted into the direction of the slit Ub through the branch hole portion 1〇c. The insertion hole l〇a of the female part 1 is inserted, and the elastic piece l〇f provided at the base 1〇 is temporarily elastically deformed. After that, the engaging convex portion 10g can be engaged with the temporary concave portion by the pressing force of the elastic piece 1〇f at the position where the engaging convex portion 1〇g is inserted into the temporary concave portion. 21d, whereby the female part 1 and the male part 2 can be combined in a state in which the female part 2 is not elastically deformed. Then, as mentioned above, eight will be organized.

The male part 2 is reused from the parent part i. Moreover, since the buckle is attached to the fastening portion and the base portion 14 318745 1303292 ίο of the female component 1 is unobstructed, the fastening projection 1 〇g is fastened to the male component buckle. When the recess 2le is engaged, the front end portion 21 can be formed by the length of the shaft portion 2ι not 2:2. Further, in the embodiment, the inner portion of the branch hole portion 1〇c located at the relative position of the through hole of the female component is inserted into the elastic piece having the engaging convex portion 1〇g. The sides of the diametrical direction of the =1〇e' 21 respectively prevent the shaft portion 21 of the male part 2 from being detached from the shank portion 11 of the shaft portion. In addition, in this embodiment, the parent part u u is less-ported, and is formed by a recess which is continuous between the convex portion and the convex portion and the concave portion formed between the convex portion In the example of the offset prevention diagram, the four 胴 constituting sheets 1 constituting the dam portion U are moved forward to prevent the surface Ilf from the portions other than the front end side and the root side. In this type of buckle, there is a 'it condition that the elastic deformation force of the first part 11 of the time-dependent parent part is lowered. (later deformation) This situation is likely to occur in the case where the components P and P that are continuously buckled are separated from each other, or the case where the buckle is exposed to a large temperature change, and the female part of the buckle 1 When the early deformation force τ falls, the buckle will be difficult to exert the repulsive force in the direction of the gap between the members ρ and ρ' due to the aforementioned force. When the members ρ, Ρ, and "Song" are generated, when one of the members ρ and ρ is a resin panel, under the severe conditions, the hole for the buckle formed on the panel is also deformed by the latent deformation of the panel. The expansion is made more conspicuous. First, a comparative buckle made of synthetic resin (hereinafter referred to as 318745 15 1303292 = Fen Photographs 18 and 19), and a buckle of the embodiment of the present invention are prepared.

Therefore, the latent deformation of the crotch portion u can be easily generated. Further, even if the elastic deformation force of the crotch portion 11 is lowered, the gap can be prevented from occurring between the members P and P by the offset preventing surface Ilf. When the members P and P' having the ring holes H 318745 17 1303292 are made of synthetic resin, the offset portion can be inserted into the hole for the buckle by elastic deformation of the crotch portion 11 toward the outer case. Η _ the main hole edge, and it is less likely to produce the gap between the components ρ, ρ. Further, in this embodiment, the offset preventing surface portion nf is formed by a strong release molding of the forming type which is expanded in the longitudinal direction of the weir portion. Specifically, 'the other side is not shown, which is formed on the side of the base 1G to be formed, and the other side is not shown, and the other side is not shown. When the direction is pulled apart, the inner-square forming type of the other forming type is used to pass through; the imaginary line X position of the straight-lined parent (the figure is shown in Fig. 14) as a parting line.
