Abstract
An operation stabilization mechanism has a first carriage to which a rotational drive force of a train wheel is transmitted and which is rotatably supported with respect to a main plate, and a second carriage rotatably supported with respect to the first carriage. A constant-force spring is provided between the first carriage and the second carriage and is configured to impart a rotational force to the second carriage so that the second carriage undergoes rotation with respect to the first carriage. An escapement/governor mechanism is mounted in the second carriage and is configured to be driven by a rotational torque generated through rotation of the second carriage and transmitted to the escapement/governor mechanism. A stopper lever is mounted to undergo rotational movement relative to the first carriage for suppressing fluctuations in the rotational torque transmitted to the escapement/governor mechanism.
