Abstract
A suspension device interposed between a vehicle body and a wheel includes a shock absorber, a suspension spring, a tube member accommodating the shock absorber and the suspension spring, a sealing member closing a one-side opening of the tube member and holding a piston rod of the shock absorber, a damping force adjustment portion, which includes a coil generating a magnetic field in a passage and a wiring penetrating the piston rod and the sealing member and conducting the coil, electrically adjusting resistance caused when an operating fluid, which is a magnetic viscous fluid whose viscosity changes by a magnetic field's action, passes through the passage allowing two chambers defined and formed by a piston in a cylinder to communicate with each other in the shock absorber, and a reaction force adjustment portion, which is mounted on the sealing member, for adjusting a reaction force of the suspension spring.
