PROBLEM TO BE SOLVED: To provide a technique which contributes to simplification of manufacturing, and reduction in a manufacturing cost.SOLUTION: A female snap button 100 can switch an unlocked state that allows separation of an engaging projection 210 of a male snap button 200 based on the rotation of a rotator 110, and a locked state that limits separation of the engaging projection. The female snap button includes; a projection holding part 120 which includes two or more movable pieces arranged so as to hold the engaging projection of the male snap button, and in which each of the movable pieces are displaced to the outside in a separation process of the engaging projection of the male snap button; a plate spring 130 which is provided outside the projection holding part, and is extended in the circumferential direction surrounding the projection holding part; and a housing member 140 in which at least the projection holding part and the plate spring are arranged. The plate spring extends longer than each of the movable pieces in the circumferential direction, and energizes to the inside each of the movable pieces displaced to the outside.SELECTED DRAWING: Figure 1 |
