PROBLEM TO BE SOLVED: To easily position, support and fix a game board. SOLUTION: The game board D in a pachinko game machine is held by a holder 70 at one end, and fixed and supported by a fixing device H at the other end, so that the game board D is freely removably set to a set holding frame 12. The holder 70 includes: a pivotal support member 74 to be attached onto the sidewall surface 12b of the set holding frame 12; and a restriction member 72 connected by hinge to the pivotal support member 74 so as to be freely rotatable. The restriction member 72 includes first and second restriction surfaces 76, 78 to be crossed in an L shape. By rotating the game board D toward the set holding frame 12 in a state where one end surface of the game board D is pressurized against the first restriction surface 76, the side end of the game board D is held between the second restriction surface 78 and the game board support surface 12a of the set holding frame 12.
