Abstract

　本発明は、屈曲振動を含む複数の振動を行うアクチュエータ本体を備えた超音波アクチュエータに関するものである。 　駆動子によるアクチュエータ本体の振動の阻害を抑制することと、アクチュエータ本体への駆動子の取付強度を確保することとを両立させる。 　超音波アクチュエータ（３）は、屈曲振動を含む複数の振動を行うアクチュエータ本体（４）と、アクチュエータ本体（４）の長辺側面（４０ｂ）に取り付けられて、アクチュエータ本体（４）の振動に従って周回運動することで駆動力を出力する駆動子（５）とを備えている。駆動子（５）は、取付用の取付面（５１）が形成されていて、取付面（５１）を介して長辺側面（４０ｂ）に面接触状態で取り付けられている。取付面（５１）の長辺側面（４０ｂ）の長手方向への幅は、駆動子（５）の長辺側面（４０ｂ）の長手方向への最大幅よりも小さい。
