Abstract

A suspension includes a shock absorber and a bushing. A piston rod of the shock absorber has a bypass path for affording communicating between two liquid chambers partitioned by a piston inside a tube and two paths formed above the bypass path. A bushing inner tube connected to the piston rod has two paths communicating respectively to two paths in the piston rod. A bushing is disposed diametrally outside the bushing inner tube, interposed between the bushing inner tube and a car body and has two fluid chambers communicating respectively to two paths in the bushing inner tube. A valve body for adjusting the damping force of the shock absorber and the spring constant and damping force of the bushing is disposed in the piston rod.
