Abstract
A driving apparatus comprises: an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line; a driving shaft mounted on one end of the electromechanical conversion element in the extending direction; a driven member frictionally engaged with the driving shaft; a holder that supports the electromechanical conversion element and comprises a bearing portion for the driving shaft; and an inclination adjusting mechanism, disposed in the bearing portion, that adjusts inclination of the driving shaft with respect to the fiducial line.
Claims14
A driving apparatus comprising:
- an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line;
- a driving shaft mounted on one end of the electromechanical conversion element in the extending direction;
- a driven member frictionally engaged with the driving shaft;
- a holder that supports the electromechanical conversion element and comprises a bearing portion for the driving shaft;
- and
- an inclination adjusting mechanism, disposed in the bearing portion, that adjusts inclination of the driving shaft with respect to the fiducial line.
A method for manufacturing a driving apparatus,
- the driving apparatus comprising:
- an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line;
- a driving shaft mounted on one end of the electromechanical conversion element in the extending direction;
- a driven member frictionally engaged with the driving shaft;
- and a holder that supports the electromechanical conversion element,
- the method comprising adjusting inclination of the driving shaft with respect to the fiducial line before an adhesive for supporting the electromechanical conversion element in the holder is hardened.
A driving apparatus comprising:
- an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line;
- a driving shaft that is mounted on one end of the electromechanical conversion element in the extending direction and comprises a hollow portion at at least one of end portions of the driving shaft;
- a driven member that is frictionally engaged with the driving shaft;
- a holder that supports the electromechanical conversion element and comprises a bearing portion for the driving shaft;
- and
- a support member, mounted in the bearing portion, that comprises a fixed portion to be fixed in the holder and a fitted portion to be fitted in the hollow portion of the driving shaft.
A driving apparatus comprising:
- an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line;
- a driving shaft mounted on one end of the electromechanical conversion element in the extending direction;
- a driven member frictionally engaged with the driving shaft;
- a holder that supports the electromechanical conversion element and comprises a bearing portion for the driving shaft;
- and
- a regulating member, disposed in the bearing portion, that regulates inclination of the driving shaft with respect to the fiducial line.
