PURPOSE: A rear semi-trailing arm bush of a vehicle is provided to generate toe-in movements by the shape change of the bush when lateral force is applied on wheels, to improve the ground contacting force of rear wheels, and accordingly to improve operation stability and quality of products. CONSTITUTION: A rear semi-trailing arm bush of a vehicle is composed of a cylindrical bush(300) positioned in a holder(150) of a rear semi-trailing arm(100) to support the rear semi-trailing arm to a sub frame(200). The inside of the bush is eccentric forward and the outside is eccentric backward, and consequently, the bush forms a constant angle. In addition, the bus is penetrate-combined to a bracket(210) fixed to the sub frame by a combining device(220) to elastically support the rear semi-trailing arm to the sub frame.
