The inclined curved surfaceis disposed on a side, of a side surface of the finger hook portion, connected to the cylinder. In the inclined curved surface, the inclination of a base-side region with respect to the center axis of the cylindrical portion is gentler than the inclination of an end-side region with respect to the center axis of the cylindrical portion. The end-side curved surfaceis disposed at the boundary between the end of the finger hook portion and the inclined curved surface. The end-side curved surfaceextends along the boundary.
