PROBLEM TO BE SOLVED: To easily install a mechanism plate in a short time by arranging a guide part for aligning a shaft hole and a shaft pin in a straight line when coming into contact with a hinge member arranged on the front frame side in the mechanism plate in a pachinko machine for rotatably installing the mechanism plate on the reverse side of a front frame via a hinge tool. SOLUTION: In the pachinko machine for installing a mechanism plate 5 on the reverse side of this game board 4 by a hinge tool 6 so as to be openable/ closable by installing the game board 4 on the reverse of a front frame 2 of the pachinko machine via a game board installing frame 3, the hinge tool 6 is composed of a hinge member 19 having a shaft hole 18 and a hinge member 21 having a shaft pin 20. In installing the mechanism plate 5, the shaft hole 18 and the shaft pin 20 are aligned in a straight line by applying a guide part 27 arranged on the mechanism plate 5 to the peripheral edge of a bearing plate 23 of the hinge member 19. In this state, the mechanism plate 5 is slid in a recessed groove 28 of the guide part 27 in a state of being applied to the peripheral edge of the bearing plate 23, the shaft pin 20 is fitted to and inserted into the shaft hole 28, and the mechanism plate 5 is installed on the reverse side of the game board 4 so as to be freely openable/closable.
