A damping device comprises a piston that partitions an interior of a cylinder into first and second working chambers. A flow-rate-dependent damping force generating element connects the first and second working chambers. A first pressure chamber and a second pressure chamber divided by a free piston are formed integrally with the piston. A first connecting passage connects the first working chamber and the first pressure chamber, and a second connecting passage connects the second working chamber and the second pressure chamber. By providing a relief valve that allows fluid to flow from the first working chamber into the second working chamber, an increase in the generated damping force during a high speed operation of the piston can be suppressed, regardless of a vibration frequency of the piston. |
