ABSTRACT:
An ultrasonic linear motor according to the present invention has a configuration wherein driving elements are glued at portions on faces of an ultrasonic transducer, facing one another, where rotational directions of elliptic vibrations generated on the faces are reverse one to another, a pair of guides are provided for being pressed into against the driving elements so as to hold the ultrasonic transducer therebetween, and leaf springs serving as pressing part are provided so as to narrow a spacing between the one pair of guides, whereby the ultrasonic transducer is configured as an self-moving ultrasonic linear motor which can drive by itself. Thus, driving properties of the ultrasonic transducer itself is improved, and also the size of the ultrasonic linear motor can be reduced.
