Abstract
An ultrasonic motor is provided with an ultrasonic transducer having a piezoelectric element, a holding member fixed to the ultrasonic transducer and holding the ultrasonic transducer, a pressing member pressing the holding member, and a member to be driven which is driven by frictional force between the member to be driven and the ultrasonic transducer. The pressing member has a hole portion and the holding member has a protruding portion engaged with the hole portion in a direction of pressing conducted by the pressing member. The hole portion and the protruding portion abut on each other so that the pressing member presses the member to be driven via the holding member and the ultrasonic transducer, thereby driving the member.
