Abstract:
(EN) According to the present invention, a spiral spring (5) has an inner circumferential end (5a) fixed to a rotor (3) and an outer circumferential end (5a) fixed to a plate (8) of a housing (2), and biases the rotor (3) in one direction relative to the housing (2). Protrusions (13) each have a shape that protrudes from the plate (8) and regulate the expansion of the outermost turn (5c) of the spiral spring (5) to the outside in the radial direction. Clips (6) each have a first surface (6a) that abuts the outermost turn (5c) of the spiral spring (5), and cling to the protrusions (13) with innate elasticity.
(FR) Selon la présente invention, un ressort hélicoïdal (5) possède une extrémité circonférentielle interne (5a), fixée à un rotor (3), et une extrémité circonférentielle externe (5a), fixée à une plaque (8) d'un boîtier (2), et sollicite le rotor (3) dans un sens par rapport au boîtier (2). Des saillies (13) ont chacune une forme, qui fait saillie à partir de la plaque (8), et régulent l'expansion de la spire la plus externe (5c) du ressort hélicoïdal (5) vers l'extérieur dans la direction radiale. Des pinces (6) possèdent chacune une première surface (6a), qui vient en butée contre le tour le plus à l'extérieur (5c) du ressort hélicoïdal (5), et viennent en prise avec les saillies (13), grâce à leur élasticité inhérente.
(JA) 渦巻きばね(5)は、内周端(5a)がロータ(3)に固定され、外周端(5b)がハウジング(2)のプレート(8)に固定され、ハウジング(2)に対してロータ(3)を一方向に付勢する。突起(13)は、プレート(8)から突出した形状であって渦巻きばね(5)の最外周巻目(5c)の径方向外側への広がりを規制する。クリップ(6)は、渦巻きばね(5)の最外周巻目(5c)に当接する第1面(6a)を有し、自己の弾性力で突起(13)に取り付く。
