Document Type and Number:
Japanese Patent JP7447677
Kind Code:
B2
Abstract:
To provide a piezoelectric drive device in which vibration of a vibration part is hard to escape to a support part, and which has excellent drive efficiency, a piezoelectric motor and a robot.SOLUTION: A piezoelectric drive device comprises: a piezoelectric actuator which has a vibration part provided with a piezoelectric element, a support part for supporting the vibration part, and a connection part for connecting the vibration part and the support part; a support member which connects a part located on one side of the support part with a part located on the other side thereof, and is arranged so as to partially overlap with the vibration part in planar view; and an energization member which is fixed to the support member, and comprises a spring part for energizing the piezoelectric actuator.SELECTED DRAWING: Figure 10
