ABSTRACT:
A remote operation type damping force control mechanism for a hydraulic damper including a cylinder, a piston, and a hollow piston rod having therein an oil path interconnecting a pair of chambers separated from each other by the piston in the cylinder. The mechanism comprises an adjustment rod rotatably inserted in the hollow piston rod and provided at the inner end thereof with an orifice plate having a plurality of orifices of different diameters, a remote operation part provided with an operation member, a control cable operatively integrally connected with the operation member and lead out of the remote operation part, and a driving mechanism interposed between the control cable and the adjustment rod for driving to rotate the adjust rod in accordance with the rotation of the operation member of the remote operation part. The driving mechanism has a plurality of first pins projectingly provided on an end face of the adjustment rod and a single second pin integrally jointed with the distal end of the control cable and perpendicularly engageable with the first pins.
