PROBLEM TO BE SOLVED: To provide a game machine capable of reliably stopping a presentation device at a prescribed position.SOLUTION: An accessory 802 is rotatably pivoted at the top end of an arm 810 whose one end is pivoted to a base member 801, and a guide shaft 821 provided in the accessory 802 is fitted to and inserted in a guide grove formed in the base member 801 so that when the accessory 802 is about to reach a retreat position A by a clock wise rotation of the arm 810, the rotation speed of the arm 810 is reduced since the guide shaft 821 ascends a second inclined surface of a second guide part 820b; also, when the accessory 802 reaches a first position A' of a first guide part 820a, even if the arm 810 bounces back by a repulsive force generated when the arm 810 contacts a stopper piece 824, as the guide shaft 821 is guided along a first inclined surface of an uphill inclination, a reverse movement is blocked so that the accessory 802 is kept at the retreat position A. |
