The present invention relates to a shock absorber. The shock absorber includes: a tube which has an internal operation space inside; a rod which is partially inserted into a side of the tube; a piston which is in the tube, has an end connected to the rod, and moves in response to the movement of the rod; a driving fluid which is filling the operation space and moves in the operation space on a side on the piston and the operation space on a side on the piston on the other side on the piston through a flow path between the piston and the tube; and an end cover which is rotatably connected to the other side of the tube and rotates the piston by rotating. When the piston rotates with the end cover, the area of the flow path between the piston and the tube can be changed. |
