実施例と基本的に同じ作用効果が得られる。Furthermore, in this embodiment, the projection 5 is narrow and elongated, so that its projected area is small. Therefore, at the time of mounting the upper support, the possibility that foreign matter may be caught between the ridge portion 5 and the mounting portion B1 of the vehicle body B can be reduced, so that the distance between the flange portion 24 and the mounting portion B1 of the vehicle body B can be reduced. This is advantageous for keeping the gap constant. Second Embodiment FIG. 6 shows a second embodiment of the present invention. The second embodiment has basically the same configuration as the first embodiment. However, in the second embodiment, one ridge 8 is formed between the two bolt insertion holes 25. Also in the second embodiment, the first ridge portion 8
Basically the same operation and effect as the embodiment can be obtained.

した場合であってもそれに対する抵抗性を高め得る。According to the upper support for the vehicle suspension of the present invention, the bolt insertion adjacent to the flange portion is provided.
A ridge is provided between the through holes at a distance from the bolt insertion hole.
Therefore, when the flange is mounted on the mounting part of the vehicle body, the upper surface of the ridge contacts the mounting part of the vehicle body,
The gap between the part and the vehicle body attachment portion between bolt holes of the flange portion of the outer cylinder is regulated to a constant, thereby provided adjacent
The amount of compression of the seal portion in the thickness direction between the bolt insertion holes, that is, the degree of tightening is fixed. Therefore, excessive tightening of the seal portion is avoided. Especially between the bolt insertion holes
Excessive tightening of the seal in the case is avoided. In addition, since the ridge portion is elongated, the projected area of the ridge portion itself is small, so that the mountability to the mounting portion of the vehicle body is increased, and the resistance to the lateral G or the like can be increased even when the lateral G or the like acts.
