PROBLEM TO BE SOLVED: To easily attach a game board to a game machine frame, and perform exchange. SOLUTION: A pachinko game machine is constituted such that a worker inserts the game board 27 from the front side of the game machine frame 1 to an inner area, which is enclosed by an inner guide rail 3, an outer guide rail 4, and upper and lower fixing mechanisms 15, in a posture having the game board 27 and allowing the rear surface of the game board 27 to face the game machine frame 1, when the upper and lower fixing mechanisms 15 are stopped and placed at positions apart from an opening part 2, and, then, the game board 27 is fitted to a board storage part 6 from the front side of the game machine frame 1. When a part around the rear surface of the game board 27 is brought into contact with a board receiving surface 5, the worker moves the cams 46 of the upper and lower fixing mechanisms 15 in the direction of an opening part 2 in the front side of the game machine frame 1. Then the game board 27 is fixed to the game machine frame 1. Consequently, works for fitting and fixing the game board 27 to the game machine frame 1 are performed at the same side.
