PURPOSE: A trailing arm bush unit for a vehicle is provided to improve the ride comfort by minimizing the impact force transmitted to the back and forth directions of a vehicle through the rotary movement of a bush unit. CONSTITUTION: A trailing arm bush unit(1) for a vehicle is composed of a fixed bracket, a mounting bracket, an outer pipe(10), a first inner pipe(21), a second inner pipe(23), and an insulator(25). The fixed bracket is fixed to the front end of a trailing arm. The mounting bracket is mounted to one side of the lower part of a sub frame. The outer pipe forms an outer case to be corresponded to the trailing arm and the sub frame. The first and second inner pipes form each inner case. The insulator is interposed in the outer pipe and the first and second inner pipes, and is contacted to the inner surface of the outer pipe and the outer surface of the first and second inner pipes. |
