PURPOSE: A device of generating recoil force in a sham rifle is provided to enable a user to effectively have a shooting training with sense of reality by recoil force. CONSTITUTION: A device of generating recoil force in a sham rifle comprises a cylinder(100), a solenoid valve(200), a compressor(300), a microswitch(400), an operation pin, and an operation bar. The cylinder generates recoil force, since a breechblock(30) is moved back by pneumatic pressure during firing. The solenoid valve operates a piston(103) with the compressed air. The compressor is connected to a solenoid valve and generates the compressed air. The microswitch operates the solenoid valve. The operation pin is mounted on the breechblock, receives the elastic force of the spring, and operates the microswitch.
