However, in the above-mentioned conventional mounting structure of the stabilizer 51, the stopper member 56 is required in addition to the base plate 52 and the mounting bracket 53 in order to prevent the bush 54 from coming off. However, the number of parts is increased by the amount of the stopper member 56, which causes the cost of parts to be increased. Further, since the stopper member 56 is fastened to the base plate 52 together with the mounting bracket 53, the stopper member 56 has a problem in that the assembling property is poor and the efficiency of the mounting work of the stabilizer 51 cannot be improved. In the conventional mounting structure, each component member is designed for each function, and the flange portion 52a provided on the base plate 52 for improving the rigidity is separated from the bush portion retaining flange portion 56a provided on the stopper member 56. Therefore, the flange portions 52a and 56a are arranged in opposite directions so as not to interfere with each other.

The present invention has been made in view of such an actual situation, and an object thereof is to reduce the number of parts, reduce the cost of parts, and improve the assembling efficiency. To provide.

[0006]

In order to solve the above-mentioned problems of the prior art, in the present invention, a stabilizer is attached via a bush by fastening a mounting bracket to a base plate which constitutes a vehicle body mounting portion. In the stabilizer mounting structure, a stopper portion is provided on a side portion of the base plate, the stopper portion being bent toward the mounting surface side of the stabilizer, and the stopper portion can be engaged with the end portion of the bush.

[0007]

[Operation] In the stabilizer mounting structure according to the present invention,
Since the stopper is provided on the base plate that constitutes the vehicle body mounting part of the stabilizer, and this base plate also functions as the stopper of the bush, the bush engages with the stopper of the base plate even if the bush moves during operation of the stabilizer. Therefore, it does not come off from the mounting bracket, and it is not necessary to separately provide a stopper member as in the conventional mounting structure.
