ABSTRACT:
A shock absorber of a built-in damper type is provided with a rod guide portion one end of which is fixed to an end of a cylinder for a damper, the rod guide portion slidably supporting a rod, and an oil lock piece disposed in the other end of the rod guide portion, the oil lock piece and an oil lock case defining an oil lock chamber filled with an operating oil at the maximum compression state of the shock absorber, wherein the rod guide portion is provided with an oil seal in a side of the rod to prevent outflow of the operating oil from the inside of the cylinder, and a seal ring in a side of the rod to control leakage of the operating oil from the oil lock chamber based upon the pressure of the operating oil in the oil lock chamber.
