<p>A trigger sear 206 is placed between a trigger 105 and a bolt sear 208. The engagement between the bolt sear 208 and a bolt 121 is removed by pulling the trigger 105. The bolt 121 makes reciprocating motion in the back and forth direction of the toy gun 101. While it reciprocates once, the bolt opens and closes a valve portion 130 and fires off a bullet B. When the trigger 105 is pulled, a stopper pawl 205a and a driving pawl 203b are engaged with a control plate 201 having a ratchet gear structure. In conjunction with the reciprocating motion of the bolt 121, the driving pawl 203b rotates and displaces the control plate 201 in a forward direction. When the toy gun 101 fires a predetermined number of bullets B, a sear bar 207 is displaced. The sear bar 207 moves the trigger sear 206 and causes it to break away from the bolt sear 208.</p> |
