Abstract
According to a movement of the present disclosure, 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 includes a main spring which generates torque, a balance wheel, a gear train mechanism for transmitting the torque generated by the main spring to the balance wheel, and a spring seat for moving a second wheel, for example, of the gear train mechanism in a direction to reduce the transmission efficiency of the torque between the wheels of the gear train mechanism when the torque generated by the main spring is higher than a predetermined torque (Tmax).
