PROBLEM TO BE SOLVED: To provide a game machine which cannot only prevent the fraudulence from being committed onto a game control board but can easily and accurately find the fraudulence when made actually. SOLUTION: A pin member 218 is press-fitted into the first and second insertion holes 222 and 226 being heated. In the process, a press-fitted shaft member 240 is made of a metal and the first flange part 220 having the first insertion hole 222 and the second flange part 224 having the second insertion hole 226 are made of a resin. Accordingly, when the heat (for example, 120°C) of the pin member 218 is transmitted to the first or second flange part 220 or 224 through the press-fitted shaft member 240, the first or second flange part 220 or 224 made of the resin with a low melting point begins to melt while the press-fitted shaft member 240 of the pin member 218 made of the metal with a higher melting point are kept from melting. Thus, the first or second flange part 220 or 224 melted is welded on the surface of the press-fitted shaft member 240. COPYRIGHT: (C)2009,JPO&INPIT
