PROBLEM TO BE SOLVED: To provide a hydraulic damper which can be formed light in weight and low in cost, and can avoid interference with a vehicle body side part by a spring collar which can be flexibly adapted to a variety of layouts of different vehicle types.SOLUTION: In a hydraulic damper, a part of a piston rod at an axel side is inserted into a vehicle body side cylinder 2 from below, a piston connected to an upper end part facing the inside of the cylinder 2 of the piston rod is made to slidably slide-contact with an internal periphery of the cylinder 2, a suspension spring is interposed between the cylinder 2 and the piston rod via upper and lower spring receivers, and a spring collar 22 is interposed between a vehicle body side attachment member which is connected to the upper end of the cylinder 2 and the upper spring receiver. The spring collar 22 is cylindrically arranged by circumferentially and alternately arranging a plurality of internal contact parts 22a which contact with an external periphery of the cylinder 2, and a plurality of external contact parts 22b which are bulged to the outside of a radial direction rather than the internal contact parts 22a.

    【課題】軽量で安価に成形可能で、車種毎に異なる取付レイアウトに対して柔軟に対応可能なスプリングカラーによって車体側部品との干渉を避けることができる油圧緩衝器を提供する。【解決手段】車体側のシリンダ2内に車軸側のピストンロッドの一部を下方から挿入し、該ピストンロッドのシリンダ2内に臨む上端部に結着されたピストンをシリンダ2の内周に摺動可能に摺接させるとともに、シリンダ2とピストンロッドとの間に上下のバネ受けを介して懸架スプリングを介装して構成され、シリンダ2の上端部に結着された車体側取付部材と上バネ受けとの間にスプリングカラー22を介装して成る油圧ダンパ(油圧緩衝器)において、前記スプリングカラー22を、シリンダ2の外周に接する複数の内接部22aと該内接部22aよりも径方向外方に膨出する複数の外接部22bとを周方向に交互に配置して筒状に形成する。【選択図】図2
