To provide the front door fixing structure of a game machine that easiness in handling an inter-table machine is improved and a problem on space in a hall is eliminated by unnecessitating installing the inter-table machine while setting it back compared with the game machine.

A front door 2 is openably and closably attached to the front opening part of a housing through a hinge 3. The rotary shaft 23 of the hinge is set at a position on a front side by a prescribed size from the front end face of the side panel 1a of the housing looking from its upper side, and a plate 21 extending through nearly the full length of its height direction is fitted to the side panel 1a of the housing. The plate 21 is provided with a fixed part 26 fixed to the inner face of the panel 1a and a projection part 28 projecting toward the front side of the housing to the neighborhood of a position seen from the upper side of the rotary shaft of the hinge from this fixed part 26. At the time of opening the front door, the side edge flange part 2a of the front door is rotate-displaced to be closer to the projection part of the plate.
