A linear band-shaped elastic body is obtained by applying an ultrasonic electrical signal to the piezoelectric vibrator of a linear band-shaped vibrating body obtained by joining a plurality of piezoelectric vibrators at equal intervals to a linear band-shaped elastic body. In an ultrasonic linear motor that vibrates and presses a movable body against a plurality of protrusions provided on this linear band-shaped elastic body and moves the movable body by frictional force, the piezoelectric vibrators are divided into two sets with the same polarity, and each Ultrasonic electric signals having a phase difference of π/2 are applied to the piezoelectric vibrators of the set, and a standing wave having a phase difference of π/2 is generated in the linear band-shaped elastic body.
An ultrasonic linear motor characterized in that the direction of movement of a moving body is switched by changing the sign of the phase difference between two ultrasonic electric signals to change the direction of movement of a traveling wave generated by combining standing waves. 2. The ultrasonic linear motor according to claim 1, wherein the distance from the end of the linear band-shaped elastic body to the end of the piezoelectric vibrator is set to 1/4 of the length of the piezoelectric vibrator. 3. The linear band-shaped elastic body is supported by a support having an elastic modulus not larger than that of the linear band-shaped elastic body at the nearest node from both ends, and widthwise pressure is applied to the linear band-shaped elastic body at this support part. The ultrasonic linear motor according to claim 1 or 2.
