Claims (1)
電素子を接着するとともに、他面にロータを重ね
てそれをバネ材でステータ側に圧接させ、ステー
タとロータとバネ材の各中央孔に回転シヤフトを
貫通させて、回転シヤフトがバネ材を介してロー
タと一体に回転するようにした超音波モータにお
いて、ロータと回転シヤフトとの嵌合部を互いに
円形以外の突部又は凹部を有する断面形状にして
、両者間の回り止めとなるようにしたことを特徴
とする超音波モータ。 (2) ロータと回転シヤフトとの嵌合部の突部又
は凹部では、両者間に弾性材を介在させたことを
特徴とする請求項１に記載の超音波モータ。[Scope of Claim for Utility Model Registration] (1) A piezoelectric element for generating traveling waves is bonded to one side of a disc-shaped stator, and a rotor is stacked on the other side and pressed against the stator side using a spring material, so that the stator and rotor are bonded. In an ultrasonic motor in which a rotary shaft is passed through each central hole of a spring material, and the rotary shaft rotates together with the rotor via the spring material, the fitting portions of the rotor and the rotary shaft are formed so that they are not circular. 1. An ultrasonic motor having a cross-sectional shape having a protrusion or a recess to prevent rotation between the two. (2) The ultrasonic motor according to claim 1, wherein an elastic material is interposed between the protrusion or the recess of the fitting portion of the rotor and the rotating shaft.
