Abstract

PURPOSE:To eliminate the need of mechanically moved parts and assure reliable and stable motion without a failure caused by a damage by inserting a cylinder made of a substance of a proper thermal expansion coefficient in an oil hole. CONSTITUTION:As an oil temperature rises in association with a variation in atmospheric temperature or a motion of a shock absorber, the viscosity is reduced so that a damping force produced in the vicinity of an orifice 9 and a valve 10 is also reduced. However, as a cylinder 13 is made of a substance of a higher thermal expansion coefficient than that of a piston rod 3 and fastened by the rod, a center hole 14 is contracted in association with a rise in temperature. The damping force produced in the hole 14 is increased, while the viscosity of the oil is reduced. Therefore, the reduced damping force created in the vicinity of the orifice 9 and the valve 10 can be compensated.
