Title
(EN) VIBRATING ACTUATOR
(FR) ACTIONNEUR VIBRANT
(JA) 振動アクチュエータ
Abstract
(EN)
A vibrating actuator 1 comprises: a tubular case 2; an electromagnetic drive unit 3 provided inside the case 2; a movable element 4 capable of vibrating due to the electromagnetic drive unit 3; a first damper 40a having a plurality of arm parts 52a that support the movable element 4 from an inner surface of the case 2; and an inner guide 6a positioned closer to the center of the case 2 than the first damper 40a in the direction of a vibration axis O of the movable element 4 on the inner surface of the case 2, the inner guide 6a restricting movement of the first damper 40a that exceeds a prescribed range.
(FR)
Un actionneur vibrant 1 comprend : un boîtier tubulaire 2 ; une unité d'entraînement électromagnétique 3 disposée à l'intérieur du boîtier 2 ; un élément mobile 4 apte à vibrer en raison de l'unité d'entraînement électromagnétique 3 ; un premier amortisseur 40a ayant une pluralité de parties de bras 52a qui supportent l'élément mobile 4 à partir d'une surface interne du boîtier 2 ; et un guide interne 6a positionné plus près du centre du boîtier 2 que le premier amortisseur 40a dans la direction d'un axe de vibration O de l'élément mobile 4 sur la surface interne du boîtier 2, le guide interne 6a restreignant le mouvement du premier amortisseur 40a qui dépasse une plage prescrite.
(JA)
振動アクチュエータ1は、筒状のケース2と、ケース2内部に設けられた電磁駆動部3と、電磁駆動部3により振動可能な可動子4と、ケース2内面から可動子4を支持する複数の腕部52aを有する第1ダンパ40aと、ケース2の内面であり可動子4の振動軸O方向において第1ダンパ40aよりケース2中央側に位置して、第1ダンパ40aの所定の範囲を超える動きを規制するインナーガイド6aと、を備える。
