PURPOSE: A lower arm bush of a multi-link suspension is provided to secure two independent strength values in the radius direction of the lower arm bush and two independent strength values in the conical direction of the lower arm bush for securing the handling performance, vibration damping performance, ride quality, and structural stability of components. CONSTITUTION: A lower arm bush of a multi-link suspension comprises an outer pipe(1), a middle pipe(3), an inner pipe(5), a primary buffer member(7), a secondary buffer member(9), and a projection. The middle pipe is inserted in the outer pipe with gap. The inner pipe is inserted in the middle pipe with gap. The primary buffer member is installed between the inner pipe and the middle pipe. The secondary buffer member is installed between the outer pipe and the middle pipe. The projection is formed into determined direction from the surface of the middle portion of the inner pipe.
