Abstract
A timepiece having a movement having a hammer and a hammer drive device that drives the hammer, a case that houses the movement, a sound source that produces sound by vibrating when struck by the hammer, and a striking force transmission member that can move bidirectionally between the hammer and the sound source, and transmits the striking force of the hammer to the sound source.
Claims17
A timepiece comprising:
- a movement having a hammer and a hammer drive device that drives the hammer;
- a case that houses the movement;
- a sound source that produces sound by vibrating when struck;
- and
- a striking force transmission member that moves bidirectionally between the hammer and the sound source, and transmits the striking force of the hammer to the sound source,
- the striking force transmission member including a pin that moves bidirectionally between the hammer and the sound source, a closing member that closes a space between the pin and a holding unit that supports the pin, and an urging member that urges the pin towards the hammer,
- the closing member being an annular or tubular elastic member,
- the inside edge part of the elastic member when the elastic member is annular, or one axial end part of the elastic member when the elastic member is tubular, being fixed to an outside surface part of the pin,
- the outside edge part of the elastic member when the elastic member is annular, and the other axial end part of the elastic member when the elastic member is tubular, being fixed to the holding unit.

A portable device comprising:
- a movement having a hammer and a hammer drive device that drives the hammer;
- a case that houses the movement;
- a sound source that produces sound by vibrating when struck;
- and
- a striking force transmission member that is disposed to the case and moves bidirectionally between the hammer and the sound source, and transmits the striking force of the hammer to the sound source,
- the striking force transmission member including a pin that moves bidirectionally between the hammer and the sound source, a closing member that closes a space between the pin and a holding unit that supports the pin, and an urging member that urges the pin towards the hammer,
- the closing member being an annular or tubular elastic member,
- the inside edge part of the elastic member when the elastic member is annular, or one axial end part of the elastic member when the elastic member is tubular, being fixed to an outside surface part of the pin,
- the outside edge part of the elastic member when the elastic member is annular, and the other axial end part of the elastic member when the elastic member is tubular, being fixed to the holding unit.
