PURPOSE:To select a grip position by moving it in the longitudinal direction of a barrel by a relatively simple operation and to obtain the delicate gripping feel of the grip. CONSTITUTION:A grip 7 is formed in a different material molded hollow form of two layers of a soft material and a harder material than the soft material, and a threaded part 6 is formed on the surface of a barrel 1. An inner protrusion 10 formed partly at least on the inner surface of the hollow form is brought into contact with the part 6, and disposed out of the barrel 1 to be movable in the longitudinal direction. Thus, the grip position is moved in the longitudinal direction of the barrel by a relatively simple operation to be selected and the delicate gripping feel of the grip can be exhibited. |
