PROBLEM TO BE SOLVED: To provide a game ball hitting device which is less influenced by degradation with time and in which game ball hitting stability is excellent. SOLUTION: The hitting device 2 for hitting a game ball onto a game board 1 is provided with a hitting hammer 4 pivoted so as to be swung and energized to one swinging position side and a cam 5 pivoted so as to be turned and rotated by the drive of a motor 7 or the like. The rotating cam 5 is abutted to the hitting hammer 4, the hitting hammer 4 is pressurized from one swinging position to the other swinging direction by the cam 5, and when the hitting hammer 4 reaches the other swinging position, the pressurization of the hitting hammer 4 by the cam 5 is released, the hitting hammer 4 is returned to one swinging position by the energizing force and thus the game ball is hit with the hammer part 40 of the hitting hammer 4. In the device, the hitting hammer 4 and the cam 5 are supported by the same spindle 3 and the swing center axis of the hitting hammer 4 and the rotation center axis of the cam 5 are made coaxial.
