The plastic shell portion has an inner surface, and reinforcing ribs projecting from the inner surface. The front striking member has a rear inner surface free of the reinforcing ribs projecting therefrom. By virtue of the reinforcing ribs on the plastic shell portion, the distance of the center of gravity of the hollow head body from the front striking member can be increased.
