PROBLEM TO BE SOLVED: To provide a game machine having a superior protective property to a fraudulent unlocking using a wire rod or the like. SOLUTION: A Pachinko game machine 10 includes an outer frame 11, an inner frame 12 openably/closably supported thereto, and a locking device for locking the inner frame 12 relative to the outer frame. The locking device has a cylinder lock 700 operated by a key, a sliding rod sliding operatively connected with the operation of the cylinder lock 700, and inner hook member operatively connected with the operation of the sliding rod and slidingly displaced to a locking position for regulating the opening of the inner frame 12 and a non-locking position for allowing the opening of the inner frame 12, and an inner locking member for regulating the sliding of the inner hook member. When an external force in the locking direction is applied to the inner hook member in the locking position from a component other than the sliding rod, the inner locking member regulates the sliding in the unlocking direction of the inner hook member. On the other hand, when regularly executing an unlocking operation using the key, the inner locking member is state-changed by receiving the force from the sliding rod to slide the inner hook member to the non-locking position.
