【課題を解決するための手段】
上記課題を解決するため、本発明の圧電アクチュエータは、面内方向に移動可能な接触面を持つ移動体と、該移動体の前記接触面と接触する端部と、該端部から伸びる弾性板に板状の圧電素子を貼り合わせた振動板を有する圧電アクチュエータとを有し、発振部からの交流電圧によって圧電素子が伸縮し、前記端部が長さ方向に往復運動することにより、前記移動体と前記端部の接触点が移動体の送り方向に対し、垂直方向に移動する傾斜案内部を前記移動体の接触面に設けたことを特徴とする。[0012]
[Means for Solving the Problems]
In order to solve the above problems, a piezoelectric actuator according to the present invention comprises: a movable body having a contact surface movable in an in-plane direction; an end portion contacting the contact surface of the movable body; And a piezoelectric actuator having a diaphragm in which a plate-like piezoelectric element is bonded to each other, wherein the piezoelectric element is expanded and contracted by an alternating voltage from the oscillating portion, and the end portion reciprocates in the length direction An inclined guide portion is provided on the contact surface of the movable body, and the contact point of the body and the end moves in a direction perpendicular to the feeding direction of the movable body.
【0013】
また、本発明の圧電アクチュエータは、前記傾斜案内部が前記振動体の端部の振幅よりも大きな幅の段差であることを特徴とする。[0013]
Further, in the piezoelectric actuator of the present invention, the inclined guide portion is a step having a width larger than the amplitude of the end portion of the vibrating body.
