ABSTRACT:
A snap button for attachment to a cloth is composed of male and female buttons engageable with each other. Each of the male and female buttons includes a face plate centrally from which a smashable shank projects, a snap body, and a resilient plate. The snap body has a respective one of concave socket and plug portions in which an axial shank-insertion hole, and a peripheral flange extending from a base portion of the plug and socket portions off an inner open end thereof. The resilient plate is adapted to be pierced by the shank so as to clamp the cloth between the face plate and the resilient plate. As a result, the cloth is held not only between the resilient plate and the shank but also between the shank and the snap body, and this clamp structure prevents the cloth from being removed off the each of the male and female buttons.
