PROBLEM TO BE SOLVED: To provide a game machine preventing easy loosening of a screw rotatably holding a movable member. SOLUTION: In the pachinko game machine, loosening of the screw 120 occurs comparatively less since a head 121 of the screw 120 for rotatably holding a locking lever 114 slidably contacts a slide ring 140 when the locking lever 114 is rotated and friction acting on the head 121 of the screw is reduced. Particularly, if the slide ring 140 is used for regulating loosening of the screw 120 regarding the locking lever 114 for engaging and disengaging a member (game panel 11) to a fixed member (a front face frame 90 of a frame body 80) as in the embodiment, loosening of a screw of a scarcely rotated portion can be regulated by a simple composition.
