Abstract
In an air-type shock absorber, a piston is sealing situated in a cylinder chamber. A vacuum state occurs in a piston bearing side of the cylinder chamber when a piston is pushed. Also, an air reservoir is provided at a side opposite to the piston bearing to have a sealed structure, so that a force of absorbing a shock can be increased to have the same effect as in an oil-type shock absorber. The shock absorber can be used not only at a place requiring cleanness but also in adverse environment in which the shock absorber is exposed to water or coolant, and durability of the shock absorber is also improved.
