する油圧緩衝器。 A piston rod is connected to a piston housed in a cylinder so that it can freely slide and protrude from the cylinder, and an outer tube that is elastically deformed is arranged on the outside of the cylinder, opposite to the upper chamber on the piston rod side defined in the cylinder by the piston. It communicates with the lower chamber on the side via a check valve provided on the piston.
The oil reservoir chamber formed between the cylinder and the outer tube communicates with the upper chamber via a damping valve provided at the top of the cylinder, and the oil reservoir chamber and the lower chamber are communicated via a check valve provided at the bottom of the cylinder. A communicating hydraulic shock absorber is characterized by comprising a cap that opens and closes the bottom of the outer tube, and a sealable through hole that axially passes through the cap and faces the check valve at the bottom of the cylinder. Hydraulic buffer.
