PURPOSE: A trailing arm bush of a torsion beam axle-type rear wheel suspension is provided to reduce toe-out of wheels and improve shock-absorbing ability when lateral force acts on right and left wheels. CONSTITUTION: A trailing arm bush of a torsion beam axle-type rear wheel suspension comprises inner pipes(25) vertically connected to a mounting bracket of a vehicle body; rubbers(27) attached to the outside of the inner pipe; outer pipes(29) attached to the outside of the rubber and fixed to trailing arms; and a flange(31) formed on a side of the outer pipe into an oval type. The major axis of the outer pipe is disposed in the longitudinal direction of the trailing arm. The main axis of the flange is disposed in the longitudinal direction of the trailing arm. The trailing arm bush reduces crosswise displacement of the trailing arm, while the main axis of the flange counters lateral force of wheels against the mounting bracket and therefore, toe-out is reduced and operational safety of the vehicle is improved.
