Abstract:
1. An operation stabilization mechanism comprising: 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; a second carriage rotatably supported with respect to the first carriage; a constant-force spring provided between the first carriage and the second carriage and 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 mounted in the second carriage and configured to be driven by a rotational torque generated through rotation of the second carriage and transmitted to the escapement/governor mechanism; and a stopper lever mounted to undergo rotational movement relative to the first carriage for suppressing fluctuations in the rotational torque transmitted to the escapement/governor mechanism.
