PROBLEM TO BE SOLVED: To provide an inexpensive game machine for reducing the weight of an outer frame, securing the strength and recycling the parts. SOLUTION: An ejector pin for releasing the outer frame from a metal mold is disposed in the metal mold for forming the outer frame, and the outer frame 12 is provided with a substantially cylindrical receiving part 116 to which the ejector pin can face, whereby a part provided with the receiving part 116 can be increased in wall thickness to reinforce the vicinity of the receiving part 116. Therefore, the receiving part 116 is provided on the corner part of the outer frame 12 and a locking part 84 to reinforce the corner part of the outer frame 12 and the locking part 84. The outer frame 12 is thus reinforced, so that even if the wall thickness of the integrally formed outer frame 12 is made thin, it is not necessary to separately provide a reinforcing member for reinforcing the outer frame 12. Accordingly, the number of parts can be reduced. Further in recycling, it does not take much trouble and time to disassemble the machine. COPYRIGHT: (C)2004,JPO&NCIPI
