PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing energy consumption of driving means.SOLUTION: In a first arm 500, an angle formed by a straight line L1 and a straight line L2 becomes larger as it goes closer to a first position shown in Fig.22 from a predetermined position. Therefore, when external force is acted on the first arm 500, the closer the first arm 500 is to the first position, the smaller force components in the direction for rotating a gear member 700 can be. As a result, when the first arm 500 is held at the first position, driving force necessary at a driving motor (driving means) for resisting the external force (for example, gravitational force) acting on the first arm 500 can be made to be smaller, and suppression of energy consumption of the driving motor can be achieved accordingly. |
