Title (EN) ACTUATOR
(FR) ACTIONNEUR
(JA) アクチュエータ
Abstract: front page image
(EN) An actuator (1) is provided with a movable part (120), a support part (110, 210) that supports said movable part, and a plurality of torsion bars (230) that: (i) each connect the movable part and the support part to each other in a long direction such that the movable part can swing about an axis of rotation in said long direction; and (ii) are arranged in a short direction. The farther each torsion bar is from the axis of rotation, the lower the spring constant of that torsion bar is.
(FR) On décrit un actionneur (1) muni d'une pièce mobile (120), d'une pièce de support (110, 210) portant cette pièce mobile, et d'une pluralité de barres de torsion (230) qui: i) raccordent chacune la pièce mobile et la pièce de support l'une à l'autre dans un sens longitudinal où la pièce mobile peut effectuer un balancement autour d'un axe de rotation; et ii) sont agencées dans une direction courte. Plus une barre de torsion est éloignée de l'axe de rotation, plus faible est sa constante d'élasticité.
(JA)  アクチュエータ(1)は、可動部(120)と、可動部を支持する支持部(110、210)と、(i)夫々が、長手方向に沿った回転軸を中心として可動部が揺動可能なように、長手方向に沿って可動部と支持部とを接続すると共に、(ii)短手方向に沿って配列される複数のトーションバー(230)とを備えており、複数のトーションバーの夫々のバネ定数は、夫々のトーションバーが回転軸から遠くなればなるほど小さくなる。
