Abstract
A driving apparatus comprises: an electro-mechanical conversion element; a driving member that reciprocates in response to an extension and contraction of the electro-mechanical conversion element; and a driven member, frictionally engaged with the driving member, that moves by reciprocating the driving member, wherein the driving member comprises a shaft portion which extends in a direction of extension and contraction of the electro-mechanical conversion element in a position which lies on a side of the electro-mechanical conversion element, and the driven member is frictionally engaged with the shaft portion.

A driving apparatus comprising:
- an electro-mechanical conversion element;
- a driving member that reciprocates in response to an extension and contraction of the electro-mechanical conversion element;
- and
- a driven member, frictionally engaged with the driving member, that moves by reciprocating the driving member,
- wherein the driving member comprises a shaft portion which extends along a lateral side of said electro-mechanical conversion element in a direction of extension and contraction of the electro-mechanical conversion element, so that a perpendicular line through said lateral side intersects said shaft,
- the driven member is frictionally engaged with the shaft portion, and
- a weight member is attached to an end portion of said electro-mechanical conversion element.
