PROBLEM TO BE SOLVED: To solve a problem that a high pressure gas container is easily dislocated contrary to intention a displaying direction of using and not using of the gas container becomes problem in the case of attaching the same to a body case using an adapter in a bayonet system.SOLUTION: An attaching/detaching mechanism includes a body case (1) and an adapter (2). The body case (1) has an attaching opening (3) of the adapter (2). The adapter (2) is a cylindrical body having a shaft hole (4), one end part of the same is an attaching part (5) of a high pressure gas container (B) and the other end of the same is an introducing part (7) of a firing pin transmission shaft (6). An engaging mechanism (10) of a bayonet type is dividedly arranged in an outside wall face (8) of the introducing part (7) side and in an inside wall face (9) of the attaching opening (3). The introducing part (7) side has a display window (11) in a position where the display window is opened outside even in a condition where display window is attached to the attaching opening (3). Further, body case (1) has a lock mechanism (12) for maintaining an engaging state of the engaging mechanism (10) in the attaching opening (3). |
