PROBLEM TO BE SOLVED: To provide a game machine which prevents a lock from fraudulently being unfastened by inserting a wire or the like from a clearance between a housing and a front door and sliding a sliding plate to an unlocking position. SOLUTION: The game machine has a lock to lock the front door in the housing. The housing is provided with a plurality of projecting pieces. The lock has a cylinder lock has a sliding plate which slides in association with the operation of the cylinder lock and a plurality of claws to lock the front door to the housing by engaging with the projecting pieces. A pushing piece is projectingly provided in the sliding plate. When the sliding plate slides to an unlocking position, the pushing plate pushes corresponding locking claws and simultaneously releases the engagement of the locking claws with the projecting pieces. The periphery of the pushing piece is made up of a pressing section which presses the locking claws when the sliding plate slides to the unlocking position and a slipping section as the periphery of the pushing piece other than the pressing section. The slipping section is formed into such a shape that prevents a fraudulent tool from being engaged even if any attempt to drag the sliding plate to the unlocking position by engaging the fraudulent tool with the slipping portion is made.
