Abstract:
(EN) In the present invention, a sensor holder (12) to be attached to a first lateral surface part (10) of a first member (3) is configured such that a sensor substrate part (16) is fixed to an annular housing part (15) that overlaps in the axial direction with the first lateral surface part (10) of the first member (3). An encoder (13) to be attached to a first lateral surface part (11) of a second member (4) comprises an outward flange part (26) that extends in the lateral direction of the housing part (15) from an annular base part (25) that overlaps in the axial direction with the first lateral surface part (11) of the second member (4) and a magnetic track part (27). When a cylindrical part (33) of a cap (14) is attached to the outer periphery (22) of the housing part (15), an inward flange part (34) of the cap (14) is positioned in the lateral direction from the outward flange part (26), and a labyrinth passage (35) is formed by the cap (14) and encoder (13).
(FR) Dans la présente invention, un support de capteur (12) devant être fixé à une première partie surface latérale (10) d'un premier élément (3) est conçu de sorte qu'une partie substrat de capteur (16) est fixée à une partie logement annulaire (15), qui chevauche dans la direction axiale la première partie surface latérale (10) du premier élément (3). Un codeur (13) devant être fixé à une première partie surface latérale (11) d'un second élément (4), comprend une partie rebord extérieur (26) qui s'étend dans la direction latérale de la partie logement (15) depuis une partie base annulaire (25) qui chevauche, dans la direction axiale, la première partie surface latérale (11) du second élément (4) ; et une partie piste magnétique (27). Lorsqu'une partie cylindrique (33) d'un capuchon (14) est fixée à la périphérie externe (22) de la partie logement (15), une partie rebord intérieur (34) du capuchon (14) est positionnée dans la direction latérale par rapport à la partie rebord extérieur (26), et un passage labyrinthique (35) est formé par le capuchon (14) et le codeur (13).
(JA) 第一部材(3)の一側面部(10)に取り付けるセンサホルダ(12)は、第一部材(3)の一側面部(10)に軸方向に重なる環状のハウジング部(15)にセンサ基板部(16)を固定したものとする。第二部材(4)の一側面部(11)に取り付けるエンコーダ(13)は、第二部材(4)の一側面部(11)に軸方向に重なる環状のベース部(25)からハウジング部(15)の側方へ延びる外向きフランジ部(26)と、磁気トラック部(27)とを有する。キャップ(14)の筒部(33)をハウジング部(15)の外周(22)に取り付けると、キャップ(14)の内向きフランジ部(34)が外向きフランジ部(26)の側方に位置し、キャップ(14)とエンコーダ(13)とによってラビリンス通路(35)が形成される。
