To improve various performance or maintainability.SOLUTION: A game machine includes a door body, a main body, and a door lock mechanism which transitions from an unlock state to a lock state by engagement of a locking part with a locked part. The door lock mechanism has an accommodation part which can accommodate the locking part, and can be brought into a predetermined state in which one metal piece is inserted into a slit-like space formed by the locking part accommodated in the accommodation part and an inner wall of the accommodation part. In the predetermined state, even if somebody tries to close the door body, the one metal piece comes into contact with the locked part earlier than the locking part, thereby not resulting in the lock state. An open state of the door body is thus maintained. The one metal piece is a set key, a game token, or a 500 yen coin.SELECTED DRAWING: Figure 264-1
