Title
(EN) STEERING DEVICE
(FR) DISPOSITIF DE DIRECTION
(JA) ステアリング装置
Abstract
(EN)
A steering device (100) comprises: a rack shaft (30) that steers a wheel (1); bushings (35, 36) that support the rack shaft (30) in a slidable state; tie rods (41a, 41b) coupled with the rack shaft (30); and boots (37a, 37b) that cover areas where the rack shaft (30) and the tie rods (41a, 41b) are coupled. A projecting part (35c) is formed in one of (i) the bushings (35, 36) and (ii) a rack housing (31), and a regulating groove (32b) into which the projecting part (35c) is inserted is formed in the other. A space within a first boot (37a) and a space within a second boot (37b) constantly communicate through the regulating groove (32b).
(FR)
L'invention concerne un dispositif de direction (100) qui comprend : un arbre de crémaillère (30) qui dirige une roue (1) ; des bagues (35, 36) qui soutiennent l'arbre de crémaillère (30) dans un état coulissant ; des tiges de liaison (41a, 41b) accouplées à l'arbre de crémaillère (30) ; et des gaines (37a, 37b) qui couvrent des zones où l'arbre de crémaillère (30) et les tiges de liaison (41a, 41b) sont accouplés. Une partie saillante (35c) est formée dans (i) les bagues (35, 36) et/ou (ii) le boîtier de crémaillère (31), et une rainure de régulation (32b) dans laquelle est insérée la partie saillante (35c) est formée dans l'autre. Un espace à l'intérieur d'une première gaine (37a) et un espace à l'intérieur d'une seconde gaine (37b) communiquent constamment à travers la rainure de régulation (32b).
