Abstract
An ultrasonic motor comprising an ultrasonic vibrator having a pair of resonators for transferring and enlarging ultrasonic vibration, an electro-mechanical energy converter arranged between the pair of resonators, for generating ultrasonic vibration by application of alternating voltage, and a fastening element for crimping and fixing the pair of resonators and the electro-mechanical energy conversion element to each other, and an element to be driven crimped to an end of at least one of the resonators and driven by elliptic vibration which is generated at the ends. The electro-mechanical energy converter element is a pair of sliding vibrators which are polarized respectively in a pair of directions which are perpendicular to an axial direction and which are shift 90.degree. from each other.
