PROBLEM TO BE SOLVED: To provide a game machine for improving the working efficiency of recycling in the constitution for installing a plurality of game machine parts formed of different construction materials by a fixing part. SOLUTION: A machine screw 140 has a thread 142a for engaging with installing holes A1 and B1 bored in parts A and B formed of the different construction materials, and is molded by a shape memory polymer deformed to a second form (a shape indicated in Fig. (C)) for releasing engagement with the installing holes A1 and B1 by retreating the thread 142a from a first form (a shape indicated in Fig. (B)) for engaging the thread 142a with the installing holes A1 and B1 by heating, and the mutual parts A and B are installed and fixed by the machine screw 140 of the first form. Thus, the working efficiency of recycling can be improved by the constitution for installing the plurality of game machine parts formed of the different construction materials by the fixing part.
