To provide a piezoelectric motor which properly holds a vibration body without increasing the size of the piezoelectric motor and complicating the structure.
A first guide shaft and a second guide shaft, which are provided at the side of a housing case housing a vibration body so as to be arranged in parallel with a stretching manner of the vibration body, are disposed at the opposite sides in a bending direction of the vibration body sandwiching the housing case. Further, a first guide part slidably engaging with the first guide shaft and a second guide part slidably engaging with the second guide shaft are provided at the support base side. The structure guides a moving direction of the housing case relative to a support base, and the housing case is biased in a stretching direction of the vibration body by an elastic member fitted in the first guide shaft or the second guide shaft. The structure properly transmits a driving force of the vibration body to an object and thereby realizes accurate driving of the object without needing a large scale structure.
