PROBLEM TO BE SOLVED: To provide a game machine for effectively performing correction absorption, such as ricketiness or shake of a movable part, by adopting a simple and inexpensive configuration whereas a cantilevered movable part which is likely to cause ricketiness, a shake, or the like when lifted is used. SOLUTION: A movable performance device 50 includes: a lift drive part 55 for supporting a front end part 56a of an arm part 56 so that the front end part can be lift driven; an engagement part 56c provided nearer the movable part 54 side relative to a support part of the lift driven part of the arm part; a guide groove part 63 provided at the lift drive part so that it goes along a lift direction of the arm part; a movement member 64 movably placed along the guide groove part in the state that a pawl part 64a projects; and a tension coil spring 65 for urging the engagement part and the pawl part in the direction in which they are drawn. Thus, in performing lift operation of the arm part, correction absorption is effectively performed to the shake of the movable part cantilevered. COPYRIGHT: (C)2010,JPO&INPIT
