２５，２７をスタッドボルト１３に位置合わせしながら
挿通させて取付けなければならず、取付作業が極めて煩
雑になるという問題があった。In the above-described mounting structure, the heavy center member 5 is inserted from above the stabilizer 3, and the insertion holes 25, 27 of the feet 17, 19 are inserted into the stud bolt 13. There is a problem in that the mounting operation must be performed while being inserted while being aligned, and the mounting operation becomes extremely complicated.

いた。That is, since the stud bolt 13 is positioned so as to protrude from the lower surface side of the suspension member 1, the operator inserts the center member 5 while directly checking the relationship between the stud bolt 13 and the insertion holes 25 and 27 with the naked eye. The work is difficult, and if the stud bolt 13 is made as short as possible in order to prevent the center member 5 from interfering with the stud bolt 13 when the center member 5 is inserted, the operator can hardly see the stud bolt 13. Therefore, the insertion holes 25 and 27 must be aligned with respect to the stud bolts 13 by moving the rear end 15 of the center member 5 from above the stabilizer 3 to below the suspension member 1 and moving the front and rear and left and right at approximately places. This has made the assembly work extremely complicated.

さをそれ程大きくすることはできない。On the other hand, if the insertion holes 25 and 27 are made somewhat larger than the diameter of the stud bolts 13, the work of inserting the insertion holes 25 and 27 into the stud bolts 13 becomes easy. In order to secure the holes securely, the size of the insertion holes 25 and 27 cannot be so large.

The work of inserting the suspension member 1 underneath is not necessary, but if the support portions 9a and 9b are shifted rearward, both ends 3a of the stabilizer 3 from the support portions 9a and 9b.
In order to generate a sufficient torsional force, the stabilizer 3 needs to be made thicker, and the thickness of the supporting portions 9a and 9b must be made thick to support a large force. There is.
