To provide a game machine in which the strength of a bulging part covering an upper tray or the like is increased in a decoration frame provided on the front face of a game machine body.

By closing a body frame 3 to an outer frame 2 side and furthermore closing a glass door frame 4 and the decoration frame 60 to the body frame 3 side, decoration frame extension parts 64, 64 extending from the bulging part 63 of the decoration frame 60 and leg-like parts 67a, 67a extending from the lower decoration member 67 of the outer frame 2 are brought into contact with each other, so that a supporting structure supported from downward by the outer frame 2 is formed via the decoration frame extension parts 64, 64 and the leg-like parts 67a, 67a in the bulging part 63. Thus, the strength of the bulging part 63 can be reliably increased with the simple structure. Accordingly, the damage of the bulging part 63 can be prevented even when a player plays a game with a posture resting an elbow on the bulging part 63.
