大型化せざるを得ない。However, in such a conventional mounting structure of a suspension member,
Since the mounting strength of the bolt 25 (suspension member) depends on the fitting between the serration portion 25A of the bolt 25 and the bolt plate 24, in order to improve the mounting strength, the bolt plate itself must be mounted. It has to be thicker or larger.

り、ボルト25の製造が面倒である。Further, since the structure relies on the engagement between the serrated portion 25A and the bolt plate 24, the hardness of the serrated portion 25A of the bolt 25 must be increased in order to increase the resistance to the pushing force applied to the bolt 25. It is necessary to raise the fitting force with the bolt plate 24. In order to increase the hardness of the bolt 25, the bolt 25
It is necessary to perform a special treatment such as tempering when manufacturing the bolt 25, and the manufacturing of the bolt 25 is troublesome.

に時間がかかる。In addition, a thick bolt plate 24 and a lower reinforcing member 23 are interposed between the flange 25B of the bolt 25 and the bottom surface 22B of the cross member 22. Since the structure is such that the bolt 25 is indirectly abutted against the bottom portion 22B, it is difficult to obtain the vertical state of the bolt 25 with respect to the lower reinforcing member 23, and it takes time to adjust the verticality.

The upper pin 30 is fixed to the upper reinforcing member 31 by arc welding by passing the upper pin 30 through the hole 32 of the upper reinforcing member 31. For this reason, skill is required in the work of setting the verticality between the bolt 25 and the upper pin 31, and even if the verticality of the angle is accurately performed, it is necessary to consider the occurrence of looseness and missing due to long-term use. In addition, the fixing of the upper pin 30 to the upper reinforcing member 31 can be performed even if the bolt 25 and the upper reinforcing member 31 are not centered due to arc welding. In addition, it is necessary to take into account the possibility that the head of the bolt 25 may be affected by thermal distortion due to arc welding between the upper pin 30 and the upper reinforcing member 31 and the hardness or the like may be changed.
