PROBLEM TO BE SOLVED: To provide a hydraulic shock absorber which can easily fix a dust cover by using an existing part without causing an increase of the number of part items, man-hours and costs.SOLUTION: In a shock absorber 1, a part of a pinion rod 3 at a vehicle body side is inserted into a cylinder 2 at an axle side from the vehicle body side, a pinion 4 fastened to an axle-side end part which faces the inside of the cylinder 2 of the piston rod 3 is made to slide-contact with an internal periphery of the cylinder 2, a dust cover 5 which has an inside diameter larger than an outside diameter of the cylinder 2, and covers the piston rod 3 is arranged, and a vehicle body side attachment member 9 is fixed to a vehicle body side end part of the piston rod 3. Bump rubber 17 which the piston rod 3 penetrates is arranged at an axle side of the vehicle body side attachment member 9, and a vehicle body side end part of the dust cover 5 is gripped by the bump rubber 17 and the vehicle body side attachment member 9.

    【課題】部品点数や組立工数の増加とコストアップを招くことなく、ダストカバーを既存の部品を用いて簡単に固定することができる油圧緩衝器を提供すること。【解決手段】車軸側のシリンダ2内に車体側のピストンロッド3の一部を車体側から挿入し、該ピストンロッド3の前記シリンダ2内に臨む車軸側端部に結着されたピストン4を前記シリンダ2の内周に摺動可能に摺接させ、前記シリンダ2の外径よりも大きな内径を有するとともに前記ピストンロッド3を覆うダストカバー5を設け、前記ピストンロッド3の車体側端部に車体側取付部材9を固定した緩衝器1において、前記車体側取付部材9の車軸側に、前記ピストンロッド3が挿通するバンプラバー17を設け、該バンプラバー17と前記車体側取付部材9とによって前記ダストカバー5の車体側端部を挟持されることを特徴とする。【選択図】図1
