PURPOSE: A shock absorber filled with beads is provided to improve shock-absorbing performance by decreasing shock, applied to a piston, through friction. CONSTITUTION: A shock absorber filled with beads comprises a cylinder(10), oil(20), a piston(30), a spring(40), and beads(50). The cylinder is filled with the oil. The piston is installed in the cylinder to be movable, and compresses the oil by external force. The spring returns the piston to a relaxed state. The beads decrease shock by applying resistance to the descended piston. The specific gravity of the beads is bigger than the oil.
