A shock absorber includes: a cylinder accommodating a fluid; a piston that reciprocates with respect to the cylinder while partitioning an inside of the cylinder into a first fluid chamber and a second fluid chamber; a pump having a first port that communicates with either one of the first fluid chamber and the second fluid chamber and a second port that communicates with the other one of the first fluid chamber and the second fluid chamber, and including a flow rate change portion that changes a circulation amount of the fluid circulating between the first port and the second port; an electric rotor rotating in conjunction with the pump; and a stator forming a magnetic field between the electric rotor and the stator.

Shock absorber

To positively prevent a pressure medium sealed into an outer tube from leaking out from a clearance relative to an oil damper, there is provided a seal construction of a shock absorber with leveling function wherein a seal mechanism is disposed in an outer tube to slidably insert a shock absorber thereinto, a piston rod extending from the shock absorber is connected on the outer tube side, a pressure medium sealed into the outer tube is heated by a heating means and leveling is carried out while controlling the support force exerting on the shock absorber , the seal construction being constituted that a free piston is interposed opposite to the seal mechanism between the outer tube and the shock absorber , and the seal mechanism and the free piston compart and form a lubricating oil chamber therebetween whereas the free piston is always biased toward the lubricating oil chamber
