To suppress abrasion of a boot.SOLUTION: A boot 5 comprises: a housing-side bellows part 53A in which convex parts 53Aa and concave parts 53Ab are alternately continuous from a housing 10 to the end of a ball joint 3, at a neutral position of a rack 88b; and a tie rod side bellows part 53B in which convex parts 53B2a, 53B1a and concave parts 53B2b, 53B1b are alternately continuous from the end of the ball joint 3 to a tie rod 89 side. The tie rod side bellows 53B is formed so as to have a smaller thickness TB than that of the housing side bellows part 53A.SELECTED DRAWING: Figure 3
【課題】ブーツの摩耗を抑制すること。【解決手段】ブーツ5は、ラック88bの中立位置において、ハウジング10からボールジョイント3の端まで凸部53Aaと凹部53Abが交互に連なるハウジング側蛇腹部53Aと、ボールジョイント3の端からタイロッド89側に向けて凸部53B2a,53B1aと凹部53B2b,53B1bが交互に連なるタイロッド側蛇腹部53Bと、で構成されており、タイロッド側蛇腹部53Bが、ハウジング側蛇腹部53Aよりも肉厚TBが薄く形成されている。【選択図】図3
