PURPOSE: A bush unit for a suspension arm of a vehicle is provided to improve the ride comfort by reducing the friction of a suspension by preventing the rotating deformation of a bush unit. CONSTITUTION: A bush unit(1) for a suspension arm of a vehicle is composed of an outer pipe(10), a sleeve(20), plural balls(30), an inner pipe(40), and an insulator(50). At least one guide hole(11) is formed on the outer circumference of the outer pipe. At least one mounting groove(23) is formed on the center of the outer circumference of the sleeve. The balls are inserted to the mounting groove between the outer pipe and the sleeve. The insulator is contacted on the inner surface of the sleeve and the outer circumference of the inner pipe. |
