A shock absorber is provided. A first piston, a pilot valve, a second piston, and a rebound retainer are sequentially connected to a piston rod reciprocating within a cylinder. An upper portion of the second piston is arranged inside the first piston. Due to a first compression chamber formed in the first piston, a second compression chamber formed in the second piston, a third compression chamber formed between the first piston and the second piston, and a fourth compression chamber formed in the rebound retainer, it is possible to improve a ride comfort by reducing a damping force over periods from an ultra-low-speed period to a high-speed period and it is possible to achieve compact configuration and cost reduction by reducing the overall length of the processed portion. |
