<P>PROBLEM TO BE SOLVED: To provide a game machine capable of reducing screw looseness of an assembly board to improve assembly board fixing stability. <P>SOLUTION: The assembly board 410 includes a recess 483, having a through-hole 413 in which a screw 481 for screwing the assembly board 410 to a game board 30 is inserted, and provided on a predetermined place of its rear side. Under the assembly board 410 set to the game board 30 with the screw 481 inserted in the hole 413 of the recess 483, a protrusive part of the inner top of a screw fastening cap 490 set-fixed so as to cover the recess 483 comes in contact with a screw head 481a, thereby even when the screw 481 tends to loose through transportation shaking or the like, looseness of the screw 481 can be prevented by the screw head 481a coming in contact with the screw fastening cap 490, thereby reducing ball clogging or game part fixing instability on the assembly board 410 resulting from the looseness of the screw 481. <P>COPYRIGHT: (C)2012,JPO&INPIT |
