PROBLEM TO BE SOLVED: To facilitate glass plate attaching/detaching work to a glass door which is openably/closably attached to the game board to cover the game board. SOLUTION: The glass plate protected by a protection frame is tiltably supported on a fixing/supporting frame 52 fixed on the back surface side of the glass door with screws. The protection frame is composed of a lower protection frame 53 for protecting the lower part of the glass plate and an upper protection frame 55 for protecting the upper part of the glass plate. The lower protection frame 53 is supported by tilting/supporting mechanisms (52b, 53b, 52c, 53c, 61, and the like) provided at the lower part of the glass door so as to be tilted forward and backward to support the glass plate held by the protection frame so as to be changed in position between a raised angle position where the glass plate is raised vertically upwardly and an attachment/detachment angle position where the glass plate is tilted backward. The glass plate positioned at the raised angle position is locked and held at the raised angle position by locking/holding mechanisms (56, 57, 64, and the like) provided at the upper part of the glass door.
