PROBLEM TO BE SOLVED: To provide a game machine whose mechanism board does not unduly come off. SOLUTION: A mounting frame 2 for a pachinko playing board of the game machine is provided on the back of the front frame 1. The mechanism board 4 is fitted to the mounting frame 2 with a hinge fitting 5, being detachable and easily opened and closed. A part 28 for restricting an upward movement of the mechanism board 4 within the range of its turn is provided on either the frame 2 or the mechanism board 4 and an elastic segment 27 is provided on the other. By fitting the mechanism board 4 in such a manner that it is turnable against the force of the elastic segment 27, the mechanism board 4 does not get out of place.
