<p>A single cylinder type hydraulic shock absorber for a vehicle (100) includes a cylinder (1), a free piston (2) that is inserted slidably into the cylinder (1) and delimits a fluid chamber (7) and a gas chamber (8) in the cylinder (1), a piston (3) that is inserted slidably into the cylinder (1) and delimits the fluid chamber (7) into two pressure chambers (7a, 7b), a rod (4), one end of which is connected to the piston (3), and an elastic member (9) that is accommodated in the gas chamber (8) and biases the free piston (2) in the direction of the fluid chamber (7). The elastic member (9) is set such that a spring constant thereof increases during contraction.</p> |
