摘要： A mechanical component configured to rotate with a shaft member includes a component main body having a through-hole through which the shaft member is passed, and one or more shaft support portions formed on the inner surface of the through-hole to fix the shaft member to the component main body. The one or more shaft support portions protrude from the inner surface of the through-hole and are capable of retaining the shaft member due to an elastic force. The one or more shaft support portions are made of material having a larger elongation percentage than that of the material of the component main body thereby preventing breakage of the mechanical component due to stress created when the shaft member is forced through the through-hole in the component main body.

摘要： 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.
