To provide a technique which improves responsiveness of attenuation force when a contracted buffer extends.SOLUTION: A rear suspension 10 of a saddle-riding type vehicle comprises: a cylindrical cylinder 30; a piston 40 which partitions an interior of the cylinder 30 into 2 hydraulic chambers 31 and 32, upper and lower ones; a first rod 41 downwardly extended from the piston along a central axis CL of the cylinder; a first support member 42 which supports the first rod 41 so as to enable the same to be moved forward and backward; a second rod 43 upwardly extended from the piston along the central axis CL of the cylinder; a second support member 44 which supports the second rod 43 so as to enable the same to be moved forward and backward; and a pressurize section 70 which pressurizes oil in the hydraulic chambers 31 and 32. The diameter D2 of the second rod 43 is larger than the diameter D1 of the first rod 41.SELECTED DRAWING: Figure 2

    【課題】縮んだ緩衝器が伸びようとする際の減衰力の応答性を向上させる技術を提供すること。【解決手段】鞍乗り型車両のリアサスペンション10は、円筒状のシリンダ30と、シリンダ30内を上下2つの油室31、32に区画しているピストン40と、シリンダの中心軸CLに沿ってピストンから下側へ延びている第1のロッド41と、第1のロッド41を進退可能に支持する第1の支持部材42と、シリンダの中心軸CLに沿ってピストンから上側へ延びている第2のロッド43と、第2のロッド43を進退可能に支持する第2の支持部材44と、油室31、32内の油を加圧している加圧部70と、を有している。第2のロッド43の直径D2は、第1のロッド41の直径D1よりも大きく設定されている。【選択図】図2
