<P>PROBLEM TO BE SOLVED: To provide a game machine allowing reduction of increase of a returning force necessary to return a movable part to an initial position in a configuration wherein the movable part of a movable component is urged to one direction, and also variation in a return operation. <P>SOLUTION: In this game machine, a float operation unit 400 that is the movable component has: a drive shaft 407D that is the movable part capable of moving from the initial position to the one direction (a front-view clockwise direction A7); and a twist coil spring 412 that is an urging means urging the drive shaft 407D to the initial position side (counterclockwise). The float operation unit 400 includes a reduction mechanism for reducing increase of a force (the returning force) working to a direction to return the drive shaft 407D to the initial position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
