PURPOSE:To make a motion light and to obtain reality by changing over the direction of the motion of piston of a air cylinder automatically under an air pressure or a gas pressure after a bullet in a shooting part is shot by the air pressure or the gas pressure, and by sending a subsequent bullet automatically into the shooting part. CONSTITUTION:By pulling a trigger 15 in a state wherein a projection 3 is charged in a shooting part 10 of a gunbarrel 9, air or gas is supplied to an air supply part 13 of a piston 12 and the projection 3 is shot under the pressure thereof, while the piston 12 is moved back by the reaction of the shooting. Then the communication of an air supply port 6 with the air supply part 13 is cut, the direction of release of the air or the gas is changed over automatically, and when the piston 12 is moved back further to a maximum stroke approximately, a subsequent bullet 3 is made to rise to the fore end position of the piston 12 and pushed into the shooting part 10 automatically. According to this constitution, a load applied on the trigger holds down a valve alone and so a force required for pulling the trigger becomes light. |
