An ultrasonic motor includes a transducer configured to be assembled as one unit by a piezoelectric device, a holding member, and a friction contact member, a hollow rotor configured to contact the friction contact member, a first driving force transmitting member, a press member and a support mechanism. The support mechanism includes a second driving force transmitting member, a transmission shaft bearing having an inner ring in which the second driving force transmitting member is fitted, and a bearing support member configured to be disposed in the upper surface of the case member, the bearing support member supporting the transmission shaft bearing so that the second driving force transmitting member is drivable together with the first driving force transmitting member and so that the transmission shaft bearing is drivable. |
