Japanese Patent JP5668683

Kind Code:

B2

Abstract:

A piezoelectric actuator includes: a first piezoelectric device between a base member and a moving member, and that is capable of being expanded and contracted in a direction in which the first piezoelectric device intersects with a first face that opposes the moving member of the base member; a second piezoelectric device between the first piezoelectric device and the moving member, and that is capable of being expanded and contracted in a direction different from the intersecting direction; a transfer member between the first piezoelectric device and the moving member that includes a through hole piercing through in the intersecting direction, receiving amounts of expansion and contraction of the first piezoelectric device and the second piezoelectric device to transfer a driving force to the moving member; and a supporting member that pierces through the through hole, and that can support the moving member.
