Abstract
There is provided a recoil shock device capable of obtaining the same recoil shock as that in a case where the weight of a piston is increased, without increasing the weight of the piston by separately providing a movable part and a weight of a piston/cylinder. There is also provided a recoil shock device capable of obtaining a recoil shock similar to that in a real gun, without damaging the outer appearance of a gun. In order to drive a weight to obtain imitated recoil, i.e., a recoil shock by operation of a movable part in a piston/cylinder which generates compressed air, a communicating partwhich is moved in its retreating direction by the movable partis provided, and a recoil springwhich receives a force transmitted to the weightvia the communicating partby the movable partso as to be in a compressed state is provided. A reaction that accompanies movement of the weightwhen the recoil springis compressed and the recoil springis then extended by its resilient force is transmitted to a main bodyof the gun.
