    • According to a movement of the present invention, the prevention of the transmission of torque to a governor when excessive torque is generated and the prevention of the wasteful consumption of energy when the excessive torque is not generated are achieved. The movement (100) includes a main spring (1) (an example of a power source) which generates torque, a balance wheel (23) (an example of a governor), a gear train mechanism (10) for transmitting the torque generated by the main spring (1) to the balance wheel (23), and a spring seat (30) (an example of moving mechanism) for moving a second wheel (12), for example, of the gear train mechanism (10) in a direction to reduce the transmission efficiency of the torque between the wheels of the gear train mechanism (10) when the torque generated by the main spring (1) is higher than a predetermined torque (Tmax).
    • 根据本发明的运动,实现了当产生过度扭矩时防止向调速器传递扭矩并且防止当不产生过量扭矩时浪费能量消耗。 机芯(100)包括产生转矩的主弹簧(1)(动力源的一个例子),平衡轮(23)(调速器的一个例子),齿轮机构(10),用于传递产生的转矩 通过主弹簧1向摆轮23传递动力,并且例如使齿轮系机构10的第二轮12移动的弹簧座30(移动机构的一个例子) 当主弹簧(1)产生的转矩高于预定转矩(Tmax)时,降低齿轮系机构(10)的车轮之间的转矩传递效率的方向。
