Abstract

See full text

A driving apparatus comprises a plurality of vibrators vibrating by application of a high-frequency voltage thereto; a friction member in frictional contact with the vibrators; and a pressing portion for bringing the vibrators into pressed contact with the friction member. The plurality of vibrators are arranged to be juxtaposed and a single drive force is extracted by moving the plurality of vibrators relative to the friction member, and a position where the drive force is extracted is a central position of the plurality of vibrators in a direction in which the plurality of vibrators are juxtaposed and is close to a frictional contact position in a pressing direction of the pressing portion.
