Abstract
A piezoelectric motor includes: a driven member having a substantially spherical shape; a base; a support member provided on the base; a gimbal frame that is provided on a periphery of the driven member; a first bearing that couples the gimbal frame to the support member to be rotatable around a first rotation axis; a second bearing that couples the driven member to the gimbal frame to be rotatable around a second rotation axis that is orthogonal to the first rotation axis; a plurality of piezoelectric elements, each of which has one end fixed onto the base and the other end disposed to be in contact with an actuation portion that abuts the driven member; and an elastic portion that is formed on the gimbal frame, the elastic portion being displaceable in a direction orthogonal to the first rotation axis and the second rotation axis.
