Since high dimensional accuracy is required for the external fitting portion 6A and the curved portion 7A that contact the outer circumferential surface of the cylinder 2, there is a problem in that manufacturing costs increase. Further, since the mounting bracket 5 is formed from the outer bracket 6 and the inner bracket 7, the weight of the mounting bracket 5 becomes large, and there is a problem that it cannot meet the recent needs for reducing the weight of the strut 1.

The present invention has been made in view of the problems of the prior art described above, and it is an object of the present invention to provide a mounting bracket that can reduce the number of parts, simplify assembly work, and reduce weight.
