ているフロントフオーク。 A wheel-side tube is slidably inserted into the vehicle-side tube, a damper cylinder stands up within the vehicle-side tube, and a hollow piston rod is movably inserted into the damper cylinder via a piston valve that can freely float up and down. The piston valve divides the damper cylinder into two upper and lower oil chambers, and the two oil chambers are opened and closed via the inner peripheral gap of the piston valve and a notch valve provided at the bottom of the piston valve.
Furthermore, a thin walled portion is formed in the piston rod above the damper stroke range, a reservoir is defined between the tube on the vehicle body side and the piston rod, and the upper oil chamber is connected to the reservoir via a check valve provided at the top of the damper cylinder. The front fork opens and closes the lower oil chamber, and the lower oil chamber communicates with the reservoir via the lower orifice provided in the piston rod, the upper through hole, and the internal passage.
