Abstract: A bidirectional shock absorber includes a cylinder housing including a liquid chamber, a shock-absorbing mechanism located inside the liquid chamber and supported by a rod sticking out of the cylinder housing. The shock-absorbing mechanism includes a pair of pistons located in the liquid chamber and attached to the rod on the respective sides of a liquid storage chamber constituting an accumulator, resistance paths formed between an outer circumferential surface of the pistons and an inner circumferential surface of a piston chamber, to apply flow resistance to the liquid, and unidirectional flow paths formed along the respective pistons and configured to block the liquid flow toward the liquid storage chamber when the corresponding piston is pressed toward the piston chamber, but to permit the liquid to flow in the opposite direction.
