Since the bolt stop member 62 is in a shape that does not contact even when it is moved to the maximum, it does not directly contact the relay member 61. Since the bolt stop member 62 is engaged with the shaft 65 through the long hole 62b, the bolt stop member 62 can be moved with the length of the long hole 62b as the maximum limit. At the time of maximum movement, the other end portion 61b of the relay member 61 enters the groove portion 62a of the bolt stop member 62 further.

- the compressed gas flows into the differential pressure valve 18 from the gas passage 18a of the differential pressure valve mechanism 20 and is injected into the bullet B.
- the bullet B is fired from the barrel 11 (FIG. 8A). Due to the pressure of the gas continuously flowing in after the bullet is fired, the differential pressure valve 18 moves forward and the differential pressure valve mechanism 20 is closed, and the gas flow is guided to the cylinder 14 (FIG. 8B).
