In such a snap fastener, when two female and male snaps B and A are disengaged from each other by holding two flexible membranes (for example, around the front and back of clothes) C and C, respectively. A force in the direction of drawing into the through holes 3A, 3B acts on the enlarged diameter deformed portions of the protrusions 6A, 6B of the rivet members 5A, 5B which are caulked to the edges of the through holes 3A, 3B of the joining members 4A, 4B. As a result, the protrusions 6A and 6B may come off unexpectedly (the connection state of the rivet members 5A and 5B and the fitting members 4A and 4B due to the crimping of the protrusion ends may be separated).
This tendency is caused by the fact that, when the flexible film bodies C, C are made of a thick material such as jeans, the protrusions 6A, 6B at the time of caulking work.
Since the amount of protrusion of the distal end from the through holes 3A and 3B is reduced, the volume of the enlarged diameter deformed portion is reduced accordingly, and it appears more remarkably.

特徴としている。According to the present invention, a male or female fitting portion is formed on the surface of a synthetic resin substrate, and a shaft center is provided at the center of the fitting portion. A circular through-hole having an inner peripheral surface substantially parallel to the hole is formed, and a synthetic resin protrusion of a rivet member driven from one side of the flexible film body is inserted into the through-hole, and the projecting tip is hit. In the fitting member made of synthetic resin for a snap fastener, which is configured to be attached to the flexible film body by expanding and deforming the diameter in the fitting portion, the through-hole is formed on the surface side of the synthetic resin substrate and the through hole. It is characterized in that a short annular ridge is integrally formed on the edge.

When a force in the direction of drawing into the through-hole acts on the enlarged-diameter deformed portion of the projection of the rivet member that is crimped to the edge of the through-hole of each fitting member, the annular bulge is formed by the enlarged-diameter deformed portion. It is pulled down inside, and the inner diameter at the upper end position of the annular ridge, that is, the substantial inner diameter of the through hole is reduced, and the function of preventing the projection from falling off is exhibited. For this reason, it is difficult for the rivet member and the fitting member to be separated from each other by the crimping of the tip of the projection.

In some cases, the protrusion protrudes slightly toward the center of the through-hole than the peripheral surface, and the latter more remarkably exerts the above-described retaining function. The annular ridge may be continuous over the entire length of the through hole in the circumferential direction, or may be discontinuous in the circumferential direction of the through hole. Further, the surface of the synthetic resin substrate around the through hole may be flat (perpendicular to the axis), and may be formed on a trumpet-like inclined surface that is upwardly inclined above the edge of the through hole. Alternatively, a rising inner peripheral surface that is concentric with the through hole and substantially parallel to the inner peripheral surface of the through hole may be formed at the upper end of the trumpet-shaped inclined surface.
