Abstract
A piezoelectric motor includes a driven body configured to rotate around a rotation axis, a first piezoelectric vibrator configured to transmit a driving force to the driven body, a moving mechanism configured to move the first piezoelectric vibrator in directions approaching and separating from the rotation axis, and a second piezoelectric vibrator configured to transmit a driving force to the moving mechanism. The moving mechanism includes a screw shaft disposed along the directions and configured to rotate around an axis with the driving force of the second piezoelectric vibrator and a holding section configured to screw with the screw shaft and hold the first piezoelectric vibrator.
