PROBLEM TO BE SOLVED: To provide a game machine having a push button switch device capable of securely rotationally driving a push button when the push button is returned after moving in a pressing direction to make the push button to be pressed rotatable for improving the presentation effect.SOLUTION: A push button switch device 10 includes: a pressed operation member 16 provided movably from an origin position in a prescribed direction; and a rotational driving device 17 for rotating the pressed operation member 16 around a center axis along the prescribed direction. The push button switch device further includes a drive gear 19 and a driven gear 23 to transmit the rotational driving force to the pressed operation member 16. The push button switch device further includes a flange part 33 for rotatably supporting the driven gear 23 and controlling movement of the driven gear 23 in the prescribed direction. A notch 50 is provided in the driven gear 23, and a projecting bar 51 to be engaged with the notch 50 immovably in the circumferential direction but movably in the axial direction is provided in an optical member 24 of the pressed operation member 16. |
