Patent ID: 7084550

Claim:
A vibration wave linear motor, comprising: a vibrator having a vibrator unit configured to comprise a piezoelectric unit, and driving contacting parts respectively provided on two opposed surfaces of the vibrator unit; a first guide member contacting the vibrator via a driving contacting part on one of the two opposed surfaces; a second guide member guiding a lens frame which supports an optical element to move in a predetermined direction, contacting a driving contacting part on the other of the two opposed surfaces, and sandwiching the vibrator along with the first guide member; a pressing member pressing one of the first and second guide members against the other, and generating pressing forces between the first guide member and the driving contacting part on the one surface, and between the second guide member and the driving contacting part on the other surface, wherein the driving contacting parts convert a vibration generated by applying a voltage to the vibrator unit into driving force, whereby the vibrator, the first guide member, and the second guide member make a relative move.
