PROBLEM TO BE SOLVED: To safely and efficiently perform the work of replacing a support member for supporting a game board and a window in a pachinko game machine. SOLUTION: When the support member 22 is displaced in the direction to be detached from a body base 11, a locking face 33b of a lock member 33 and a locking face 11i of the body base 11 are locked in such a way that the support member 22 is temporarily fixed to the body base 11. The restraint of turning of a handle biasing part 32 by a biasing restraining member 11h is released by the displacement of the support member 22, and the handle biasing part 32 is turned clockwise in the figure by the biasing of a spring 37 so that a handle 31 is made to project upward. An operator displaces the handle 31 downward so that the lock member 33 is displaced to a lock release position to release the lock between the lock member 33 and the body base 11. The operator separates the support member 22 from the body base 11 while holding the handle 31 with the lock member 33 and the body base 11 in the lock released state. COPYRIGHT: (C)2005,JPO&NCIPI
