する油圧緩衝器のフリーバルブ構造。 In the free valve structure of a hydraulic shock absorber in which a free valve is held with play between an oil lock collar fitted on the inner peripheral surface of the lower end of a fork pipe and a rebound seat, there is a gap between the oil lock collar and the rebound seat. A valve seat is interposed which forms an oil passage in the axial direction and has a tapered surface on its upper end surface, and a free valve having a tapered surface corresponding to the tapered surface of the valve seat is provided between the valve seat and the rebound seat. The free valve structure of the hydraulic shock absorber is characterized in that a valve spring is interposed between the free valve and the rebound seat to hold the free valve with play and urge the free valve toward the valve seat side.
