Patent ID: 7778536

Claim:
A driving apparatus, comprising: an actuator having a driver disposed on one surface of a piezoelectric device having a shape of a rectangular parallelepiped; a holding member that holds the actuator; a movable member that is moved on the holding member by the driver; a restricting member that restricts a position of the piezoelectric device with respect to the holding member; an anti-vibration sheet fixed to the restricting member; and a pressing member that presses the driver disposed on the actuator against the movable member with the restricting member and the anti-vibration sheet interposed therebetween, wherein the restricting member has a protrusion that serves as a point of application of a pressing force of the pressing member at a center part in a longitudinal direction of the piezoelectric device having the shape of a rectangular parallelepiped, the anti-vibration sheet is fixed to the restricting member to cover the protrusion, and a low friction material is interposed between the anti-vibration sheet and the pressing member in a vicinity of the protrusion.
