PROBLEM TO BE SOLVED: To provide a piezoelectric motor that is free of loss of drive energy of a driven body with the passage of time.SOLUTION: In a piezoelectric motor 10, corrugated portions T are formed on respective joint surfaces of a first support section S1, a second support section S2, a third support section S3 and a fourth support section S4. On account of this, the joint surfaces are hardly offset from one another with the passage of time. Accordingly, a piezoelectric element 20 can be reliably held, and loss of drive energy of a driven body 90 can be prevented. |
