PURPOSE: A shock absorber having a stopper structure using oil pressure is provided to perform a stop function when the shock absorber is compressed without a noise or vibration by preventing the upper side of the cylinder with the chassis by using the pressure of oil. CONSTITUTION: A shock absorber having a stopper structure using oil pressure includes a cylinder, a piston valve(13) and a piston rod. A piston valve is received inside the cylinder and divides the inner side of the cylinder. One side of the piston rod is connected to the piston valve and the other side thereof is extended to the outside of the cylinder. A stopper structure prevents the upper side of the cylinder from colliding with a chassis. The stopper structure has a concave unit(21) and a pin number(23). The concave unit is formed on one side of the piston rod in a longitudinal direction. The pin member is formed inside the cylinder to be inserted into the concave unit in the compression of the shock absorber. |
