長い場合に、特に顕著である。However, when the hammer supporting the head and the caulking punch supporting the tip of the cylindrical leg are moved toward each other in the axial direction to press the tip side of the cylindrical leg, the member to be fastened has a ball. If the member is a relatively soft member, such as paper, soft synthetic resin, or jeans, the inner surface of the fastening hole formed in the member to be fastened cannot constrain the cylindrical leg portion in a fixed posture. There is a problem that the axis of the cylindrical leg portion is inclined and the cylindrical leg portion is likely to buckle. Even if the member to be fastened is a hard member, even if the inner diameter of the fastening hole previously formed in the member to be fastened is larger than the outer diameter of the cylindrical leg portion of the resin rivet, the inner surface of the fastening hole has a cylindrical shape. Since it is not possible to constrain the curved leg portion to a fixed posture, similarly, inclination (center misalignment) and buckling of the cylindrical leg portion easily occur. These disadvantages are particularly remarkable when the synthetic resin of the cylindrical leg portion of the resin rivet is soft or when the axial length of the cylindrical leg portion is long.

That is, according to the method of crimping a resin rivet according to the invention of claim 1, the cylindrical leg portion of the resin rivet having a head portion and a cylindrical leg portion projecting from a central portion of the rear surface of the resin rivet is fastened to a fastening hole of a fastening member.

The cylindrical leg portion 10b of the resin rivet 10 is fitted onto the shaft body 1. As a result, the resin rivet 10 is vertically supported by the shaft body 1, and the cylindrical leg portion 10b is constrained by the shaft body 1 in a fixed posture.

Since the hammer B supporting the head portion 10a and the caulking punch A supporting the tip of the cylindrical leg portion 10b move closer to each other in the axial direction, the caulking punch A presses the tip side of the cylindrical leg portion 10b to caulk it. As described above, since the shaft body 1 is inserted into the cylindrical leg portion 10b, as shown in FIGS. 6 to 9, the shaft body 1 serves as the cylindrical leg portion 10b.
While restraining b in a fixed posture, the caulking punch A presses the tip side of the cylindrical leg portion 10b to perform caulking. That is, the cylindrical leg portion 10b is lowered together with the hammer B and pressed against the caulking punch A while preventing misalignment and buckling by the shaft body 1 inserted inside, so that the cylindrical leg portion 10b is pressed.
The tip end side of b is expanded and deformed along the conical slope surface 3 and is rewound along the inner surface of the annular groove 4, and finally,
As shown in FIG. 9, it becomes a double flange-shaped portion and is caulked to the fastened members 11a and 11b.

る。Therefore, when the fastened members 11a, 11b are relatively soft members such as cardboard, soft synthetic resin, jeans or the like, or fastened holes a, b formed in the fastened members 11a, 11b. Even when the inner diameter of the cylindrical leg 10b is larger than the outer diameter of the cylindrical leg 10b of the resin rivet 10, inclination (center misalignment) and buckling of the cylindrical leg 10b can be reliably prevented.
Even if the synthetic resin of the cylindrical leg portion 10b of the resin rivet 10 is soft or the axial length of the cylindrical leg portion 10b is long, the inclination (center misalignment) and buckling of the cylindrical leg portion 10b do not occur and the temperature is kept at room temperature. The caulking can be performed reliably and satisfactorily.
