To provide a rear suspension structure which can harmonize both of bending rigidity and torsional rigidity.SOLUTION: A hub carrier 14 includes: a front arm section 30 which extends toward a vehicle front side and in a vehicle inside direction with respect to an axle A of a rear wheel; and a rear arm section 32 which extends to a vehicle rear side. The rear arm section 32 is connected to a lateral beam 16 extending in a vehicle width direction on a vehicle rear side of the axle A. A vehicle rear end 25 of a trailing arm 12 extending in a vehicle longitudinal direction is connected to the lateral beam 16. A rear suspension structure includes: a first bush 24 which connects a vehicle front end of the trailing arm 12 to a vehicle body; and a second bush 38 which connects the front arm section 30 to a front arm mounting section 34 provided in the trailing arm 12. A first support shaft 23 of the first bush 24 and a second support shaft 39 of the second bush 38 have axial directions arranged in mutually different directions.SELECTED DRAWING: Figure 1
【課題】曲げ剛性と捩り剛性との両者を調和することが可能なリヤサスペンション構造を提供すること。【解決手段】ハブキャリア14は、後輪の車軸Aよりも車両前方且つ車両内側方向に延びる前腕部30と、車両後方に延びる後腕部32とを有し、後腕部は32、車幅方向に延びるラテラルビーム16と車軸Aよりも車両後方で連結され、車両前後方向に延びるトレーリングアーム12の車両後方端部25をラテラルビーム16に連結し、トレーリングアーム12の車両前方端部を車体と連結する第1ブッシュ24と、前腕部30をトレーリングアーム12に設けられた前腕取付部34と連結する第2ブッシュ38とを有し、第1ブッシュ24の第1支持軸23と、第2ブッシュ38の第2支持軸39とは、軸方向がそれぞれ異なる方向に配置されている。【選択図】図1
