ABSTRACT:
A trigger sear is placed between a trigger and a bolt sear. The engagement between the bolt sear and a bolt is removed by pulling the trigger. The bolt makes reciprocating motion in the back and forth direction of the toy gun. While it reciprocates once, the bolt opens and closes a valve portion and fires off a bullet B. When the trigger is pulled, a stopper pawl and a driving pawl are engaged with a control plate having a ratchet gear structure. In conjunction with the reciprocating motion of the bolt, the driving pawl rotates and displaces the control plate in a forward direction. When the toy gun fires a predetermined number of bullets B, a sear bar is displaced. The sear bar moves the trigger sear and causes it to break away from the bolt sear.
