PROBLEM TO BE SOLVED: To provide a simply structured and inexpensive game machine capable of easily adjusting the pressing force applied to gripping arms 30 and 31. SOLUTION: In the game machine, the pressing force applied by springs 56 and 57 to the gripping arms 30 and 31, the gripping force of the gripping arms 30 and 31, is adjusted by separating oscillation members 46 and 47 (projections 44a and 45a) from the gripping arms 30 and 31 by displacing (raising) them after they reach a closing position H and by adjusting the length L from the position of separation to the position of stopping of displacement by a control means. As a result, special members such as a spring socket and an adjusting screw are not required, and the adjusting work by a worker is not necessary either. COPYRIGHT: (C)2005,JPO&NCIPI
