The arm hanger 3 is attached to the vehicle body by welding, and a front end of the trailing arm 4 is supported by a bolt 12. A first clamp 13 and a second clamp 14 are overlapped on the surface of the arm hanger 3 with the first clamp 13 facing down, and are attached by fastening bolts 15 together. The first clamp 13 supports the rear sensor harness 17 via a grommet 16, and the second clamp 14 supports the parking cable 11 via a protective pipe 18.
[0004]
Since the first and second clamps 13 and 14 are fixed by only one bolt 15, there is a possibility that the bolts 15 are rotationally displaced from each other around the bolt 15. Therefore, a part of the side of the first clamp 13 is bent to form a claw 13a. The claw 13a is brought into contact with the side of the second clamp 14, and the claw 14a is also attached to the second clamp 14. And is fitted into a hole 13b provided in the first clamp 13.

In the structure described above, as clearly shown in FIG. 9, the fuel tank 8 and the arm hanger 3 are arranged very close to each other, and there is no space for operating the tool between them. There were restrictions. That is, the assembly priority order in which the fuel tank 8 is mounted on the vehicle body after the parking cable 11 is attached to the arm hanger 3 becomes essential, which sometimes hinders the assembly work. Further, when the necessity arises and the parking cable 11 is replaced, it is necessary to remove the fuel tank 8 from the vehicle body each time.
[0006]
In order to solve this problem, the position and shape of the fuel tank 8 may be changed so that a space is created between the fuel tank 8 and the arm hanger 3, but the capacity of the fuel tank 8 is desired to be increased. The fact that the fuel tank 8 is mounted in front of the vehicle body as much as possible can avoid the influence when an unexpectedly large load is applied from the rear of the vehicle body, and as shown in FIG. 9, the muffler 9 is laid out on one side. Therefore, it is difficult to solve the above problem because, for balance, the fuel tank 8 is moved to the other side.
