Abstract
A driving mechanism comprises: (i) an actuator comprising: an electro-mechanical conversion element; a driving member which is connected to one end of the electro-mechanical conversion element and moves in accordance with elongation or contraction of the electro-mechanical conversion element; and a weight member provided on the other end of the electro-mechanical conversion element; and (ii) a driven member frictionally engaged with the driving member, wherein the actuator allows the driven member to move along the driving member, and the weight member comprises a member which reduces a resonance frequency of the actuator.
