Title: FEMALE SNAP BUTTON AND SNAP BUTTON
Abstract:
According to the present invention, a female snap (210) is provided with: a first member (40, 70) for at least partially establishing an opening (P40, P70) into which a post (105) is inserted; and a second member (10, 50, 60, 91) which is able to restrict expansion of the opening (P40, P70) in order to either increase the force needed for engagement/disengagement, or prohibit engagement/disengagement, of the post (105) with respect to the female snap (210). The extent of expansion of the opening (P40, P70) that is permitted by the second member (10, 50, 60, 91) varies depending on the relative positions of a contacting part (10m, 50m, 60m, 91m) of the second member (10, 50, 60, 91) and a contacted part (40m, 70m) of the first member (40, 70) in a peripheral direction going around the direction of insertion of the post (105) into the opening (P40, P70).
