To accomplish weight saving of a saddle-riding type vehicle in a rear wheel suspension structure that has a linkage mechanism.SOLUTION: A rear wheel suspension structure includes: a vehicle body frame 10; a power unit 20 mounted on the vehicle body frame 10; a swing arm 41 which is provided so as to be able to swing relative to the vehicle body frame 10 and which supports a rear wheel 3; a rear cushion 46 that applies swing reaction force to the swing arm 41; and a linkage mechanism 50 which couples the rear cushion 46 and the swing arm 41 to each other and which is rotatably supported by the power unit 20 independently from the vehicle body frame 10 so as to be able to swing.SELECTED DRAWING: Figure 1 【課題】リンク機構を有する後輪懸架構造において、鞍乗り型車両の軽量化を図る。【解決手段】後輪懸架構造は、車体フレーム１０と、車体フレーム１０に懸架されたパワーユニット２０と、車体フレーム１０に対して揺動可能に設けられ、後輪３を支持するスイングアーム４１と、スイングアーム４１に揺動反力を付与するリヤクッション４６と、リヤクッション４６およびスイングアーム４１を互いに連結するとともに、車体フレーム１０から独立してパワーユニット２０に揺動可能に軸支されたリンク機構５０と、を備える。【選択図】図１
