ABSTRACT:
A convex sliding portion (30) is provided on the driving surface of a vibrating member (1) formed with a frictional layer (31) on its surface. Inner and outer ridges (2c, 2b) of a contact portion (21) of a rotor (2) formed with a frictional layer (2a) on its surface are located at the inner and outer sides of the inner and outer edges of the sliding portion (30), respectively, so that the ridges (2b, 2c) of the contact portion (21) do not contact an effective contact portion (B) of the sliding portion (30).
