ドガイド部シール構造。[Claims for Utility Model Registration] A rod guide provided at the open end of a cylinder tube and having a rod insertion hole in the center; and a rod guide provided in the rod insertion hole to slidably guide a piston rod with a small gap. a guide bush; an oil seal provided on the outer end surface of the cylinder tube of the rod guide via a seal housing; and an oil seal disposed in the rod insertion hole, which is capable of coming into close contact with the inner end surface of the cylinder tube of the guide bush, and which allows the rod to be inserted. A seal ring is attached to the piston rod with a pressure relief gap between it and the inner periphery of the hole, and the inner end surface of the cylinder tube of the rod guide is designed to allow the seal ring to slightly slide in the axial direction while preventing it from coming off. A seal structure for a rod guide portion of a hydraulic shock absorber, comprising: a cover provided on a side thereof with a communication path that constantly communicates between a pressure relief gap and the inside of a cylinder tube.
