Summary:PROBLEM TO BE SOLVED: To provide a piezo-motor holding member capable of improving fixability for a piezo-motor in which at least two piezo-element are oppositely provided, without deteriorating the performance of the piezo-motor. SOLUTION: The first piezo-motor holding member 24 is constituted so as to surround three piezo-elements 233 of a first piezo-motor 23. Protrusions 241, 242 are provided on an inner wall surface 24a of the first piezo-motor holding member 24. These protrusions 241, 242 are formed so as to hold only knot portions 233a, 233b of the three piezo-elements 233 of the first piezo-motor holding member 24. The first piezo-motor 23 is fixed on the first piezo-motor holding member 24 only with the knot portions 233a, 233b. COPYRIGHT: (C)2008,JPO&INPIT
