PROBLEM TO BE SOLVED: To effectively prevent the smooth movement of a performance movable object from being blocked in a game machine in which the performance movable object is driven in the vertical direction by using a slide rail of a ball sliding type.SOLUTION: A game machine 1 includes: a performance movable object 40 attached to a game board 10 to which game balls are shot, and movable to be lifted up/down in the vertical direction; and a slide rail 50 for movably supporting the performance movable object 40 to be lifted up/down. The slide rail 50 includes: a guide member 51 extended in the vertical direction; a slider 54 to move in the vertical direction along the guide member 51 while supporting the performance movable object 40; and a plurality of balls 59 provided rollingly between the guide member 51 and the slider 54 to reduce friction. A stopper 58 for controlling descending of the balls 59 is provided either in the guide member 51 or in the slider 54. |
