ABSTRACT:
There is provided a button capable of entry and exit with respect to a base. The button has a button member, ring member, lock member, and fixed member. The button member has a shaft portion mounted in a manner that allows entry and exit with respect to the base, and an expanded-diameter portion with a shaft diameter that is larger than the diameter of the shaft portion. The ring member accommodates the shaft portion and can rotate about the axial center of the shaft portion. The lock member moves along the axial center between the ring member and the shaft portion due to the rotation of the ring member, and restricts the entry and exit action of the button member by coming into contact with the expanded-diameter portion of the button member. The fixed member is fixed to the base and stops the ring member to restrict the movement of the ring member along the axial center.
