<p>PROBLEM TO BE SOLVED: To prevent a shaft and a bearing from being damaged even when an unintended load acts on a rotary body which is pivoted on the back of a game machine body in a freely rotatable manner.SOLUTION: The game machine comprises: a rotary body (board unit 100) which is provided in a game machine body and includes a bearing part in which a bearing hole opened on an upper end face of a wall part is formed, and a shaft inserted from an opening on the upper end face of the wall part into the bearing hole perpendicularly downwards, in which the shaft is pivoted by the bearing part in a freely rotatable manner and which is opened/closed between a closing position and an opening position which are predetermined; and a tilt part 55 which is provided in a movement track range of the rotary body and tilted from a perpendicular lower side to a perpendicularly upper side in an opening direction at the predetermined opening position of the rotary body. The rotary body has the relationship where, when a part (rib 113a) of the rotary body rides on the tilt part 55 in an opening process from the closing position to the opening position, the rotary body is slid perpendicularly upwards and the shaft of the rotary body is dropped out of the bearing hole by the perpendicularly upward sliding.</p> |
