設けたことを特徴とするステアリングダンパ。 A piston is slidably housed in a cylinder to define oil chambers on both sides of the piston, and a piston rod made of a hollow pipe is slidably supported at one end of the cylinder, and the oil chambers on both sides of the piston are placed on the piston rod side. It is connected via a check valve that prevents the backflow of hydraulic oil from the oil chamber on the opposite side to the oil chamber on the opposite side, and an oil sump chamber is provided on the outer periphery of the cylinder to compensate for oil volume fluctuations caused by changes in the volume of the piston rod. A damping force generating means is provided in the passage connecting the oil sump chamber and the oil chamber on the piston rod side, which throttles the hydraulic oil flowing into the oil sump chamber to provide resistance and generate a damping force. A check valve is installed in the passage that communicates the oil chamber to prevent the backflow of hydraulic oil to the oil reservoir chamber, while a hydraulic oil is filled in the protruding end of the piston rod to communicate with the oil chamber on the opposite side through a hollow part. A steering damper characterized by having an air bleed valve connected to the oil reservoir chamber on the bottom wall of the cylinder.
