At the time of molding the head body 2, a flange 1 b formed above the leg 1 a of the mounting member 1 is wound into the head body 2 by insert molding means as shown in FIGS. 5 and 6. In addition, the rotation preventing member 2a composed of a plurality of ridges is radially protruded from the back surface of the head main body 2 to form the mounting member 1 and the head main body 2 in this manner. It is one that constitutes the head H of the female body in the integrated snap button.

As shown in FIGS. 7 and 8, the head H of the female body in the snap button having the above-described structure is formed by piercing the leg 1a of the mounting member 1 into a required portion of the cloth C. At the same time, it is inserted into the central hole S ₁ of the known seat plate S of the female body, is fitted into the downwardly concave portion S ₂ curved on the back side of the seat plate S, and is caulked to be attached to the clothing material C. FIG. 9 shows a known male body O of the snap button fixed to a required portion of the clothing C in a state where the female body M is formed in the snap button.

Next, the operation and effects of the embodiment of the female head H in the snap button configured as described above will be described.

(1) The head main body 2 is made of a polyamide resin having excellent dyeing properties and so-called "post-dyeing" and moderate softness, so that it is adapted to the color and pattern of the clothing material. A variety of colors can be used, and a variety of colors can be developed in the head of the snap button, and the decorative value of the snap button can be easily remarkably improved. Combined with the ease of installation, it is possible to improve the detent effect by making good contact with the clothing material C.

(2) Since the mounting member 1 is made of a polyacetal resin which is tough, rugged and has excellent wear resistance and strong elasticity, the leg 1a may break during use and come off the seat plate S. , And can withstand long-term use.

(3) Since the flange 1b of the mounting member 1 is integrally wound into the head main body 1 by insert molding means when the head main body 2 is formed, the bonding strength between the two members is large. There is no danger of withdrawal.
