Abstract
A double-rod type shock absorber includes a rod, first and second pistons held by the rod, first and second piston chambers disposed on an outer side of the first and second pistons, a liquid storage chamber between the first piston and the second piston, a flow path gap formed between an outer peripheral surface of the first and second pistons and an inner peripheral surface of the liquid chamber, and first and second unidirectional flow paths which connect the first and second piston chambers with the liquid storage chamber, wherein, during reciprocating motion of the rod, the unidirectional flow path located on a front side in a movement direction of the rod is closed, and the unidirectional flow path located on a back side in the movement direction of the rod is opened.
