PROBLEM TO BE SOLVED: To decrease a play in a neutral position of an operating lever 30. SOLUTION: A switch 10 for a game comprises frame 20, the operating lever 30 and a neutral returning means 40. The operating lever 30 swings upward and downward relative to the frame 20. The natural returning means 40 includes a return spring 41 and a spring receiving member 42. The return spring 41 allows the spring receiving member 42 to press the frame 20 so that the operating lever 30 is returned to the neutral position. The spring receiving member 42 has a pressing contact surface 44 pressing in contact with the frame 20. The frame 20 has a surface 23 to be pressed by the spring receiving member 42. Either the pressing contact surface 44 or the surface 23 to be pressed is formed in a protruding shape which protrudes gradually toward the other side as it goes to the central part from upper and lower ends. The other is formed in a recessed shape corresponding to the one of them when the operating lever 30 is located at the neutral position. COPYRIGHT: (C)2004,JPO
