PROBLEM TO BE SOLVED: To realize attachment onto a differential apparatus without positional offset of an inner cylinder relatively to an outer cylinder even in a case where there is a gap between the inner cylinder and the differential apparatus.SOLUTION: When a bolt 42 is screwed into a screw hole 44 on a differential apparatus 10 under a state where an outer cylinder 22 is fixed onto a suspension member 20, an arm 50 is brought into contact with one end part of the outer cylinder 22 and the differential apparatus 10 is drawn to the side of the inner cylinder 24 along with screwing of the bolt 42. When the bolt 42 is further screwed into the screw hole 44 under a state where the differential apparatus 10 contacts with the inner cylinder 24 and the arm 50 contacts with the inner cylinder 24, fastening load is increased, a notch 56 part is destructed, and a head part 46 of the bolt 42 enters the inner cylinder 24 to contact with a bottom wall 38, resulting in that the inner cylinder 24 is rigidly engaged onto the differential apparatus 10 by means of the head part 46.SELECTED DRAWING: Figure 4

    【課題】内筒とディファレンシャル装置との間に隙間がある場合でも、外筒に対して内筒が位置ずれすることなくディファレンシャル装置に組み付けることができるようにする。【解決手段】外筒22がサスペンションメンバ20に固定された状態で、ボルト42がディファレンシャル装置10のねじ穴44に螺合される際に、外筒22の一端部にアーム50が当接させられることにより、ボルト42の螺合に伴ってディファレンシャル装置10が内筒24側へ引き寄せられる。ディファレンシャル装置10が内筒24に当接させられるとともに、内筒24にアーム50が当接させられた状態で、更にボルト42がねじ穴44に螺合されると、締結荷重が上昇してノッチ56部分で破断させられ、ボルト42の頭部46が内筒24内に進入して底壁38に当接させられるようになり、その頭部46によって内筒24がディファレンシャル装置10に対して強固に締結される。【選択図】図4
