In an imitation gun which generates compressed air by the action of a piston cylinder mechanism and injects and fires the compressed air from a nozzle into a bullet loaded in a barrel, this bullet feed port opening and closing device is provided with a connecting member (63) which retracts the nozzle accompanying the action of a movable part of the piston cylinder mechanism, and, in order to open a bullet feed port (62) which communicates with the front of the nozzle, transmits the aforementioned action of the movable unit to the nozzle. The linking member comprises multiple parts, which are divided into movable unit-side parts and the nozzle-side parts. A nozzle-side part and a movable unit-side part are configured to be capable of engaging and disengaging by means of an engagement mechanism (65), such that the nozzle-side part and the movable unit-side part retract as a single body to open the bullet feed port, and, after the nozzle-side component is separated from the movable unit-side part, which continues to retract, an open state is maintained for a fixed period of time, and thereafter, the movable unit-side part forms a single body with the nozzle-side part due to the forward motion of the movable unit-side part. |
