PURPOSE: A lower arm bush unit for a vehicle is provided to improve the ride comfort of a vehicle by maximizing strength to a horizontal load and minimizing strength to a vertical load. CONSTITUTION: A lower arm bush unit for a vehicle comprises an outer pipe(10), an inner pipe(30), and an insulator(50). The inner pipe is arranged inside the outer pipe. The insulator is attached on the outer pipe of the inner pipe and the inner surface of the outer pipe. Operation holes(51) are formed in both sides of the insulator. Inner protrusions(61) are formed in both sides of the outer surface of the inner pipe. Outer protrusions(71) corresponding to the inner protrusions are formed on the inner surface of the outer pipe. |
