Abstract

　圧電素子が弾性限界を超えて変形して破損することを防止する。 　超音波アクチュエータ（２）は、アクチュエータ本体（４）と、ケース（５）と、支持ユニット（６）とを備えている。支持ユニット（６）は、ケース（５）とアクチュエータ本体（４）との間に配設されてアクチュエータ本体（４）の振動の非ノード部においてアクチュエータ本体（４）に対して縦振動の振動方向へ両側から圧縮力を予め付与する２つの支持ゴム（６１，６１）及び連結ゴム（６３）を有している。連結ゴム（６３）は、中央部（６４ａ，６４ａ）及び両端部（６４ｂ，６４ｂ）と中央部（６４ａ，６４ａ）及び両端部（６４ｂ，６４ｂ）よりも剛性が低い薄肉部（６７，６７，…）とを有している。予圧ユニット（６）は、ケース（５）とアクチュエータ本体（４）との間に配設されるときには、少なくとも連結ゴム（６３）が薄肉部（６７，６７，…）において圧縮変形している。
