Abstract

Official abstract text for this publication.

A vibration type motor includes a vibrator, a friction member extending in a predetermined direction and including a first surface in pressed contact with the vibrator and a second surface positioned on a side opposed to the first surface and a holding member holding the friction member. The first surface forms with a surface adjacent thereto a first corner portion extending in a direction parallel with the predetermined direction, the second surface forms with a surface adjacent thereto a second corner portion, the first corner portion is different in radius of curvature from the second corner portion, either one of the first surface and the second surface is in contact with the holding member, either one of the first corner portion and the second corner portion has a radius of curvature smaller than the other.
