To harmonize both an amount of twist of a cross beam and an amount of displacement of a trailing arm.SOLUTION: A pair of left and right hub carriers 14a, 14b includes: a forearm part 30 that extends in a vehicle width direction and inward direction of a vehicle behind a rear wheel axle A; a rear arm part 32 extending further to the rear of the vehicle than the forearm part 30; and a first connecting part that is a pair of left and right third bushes 26a, 26b that connects a vehicle rear end part 25 of trailing arms 12a, 12b extending in a longitudinal direction of the vehicle to a lateral beam 16. The lateral beam 16 includes: a left beam 17a extending inward in the vehicle width direction from the hub carrier 14a located on a left side of the vehicle; a right beam 17b extending inward in the vehicle width direction from the hub carrier 14b located on a right side of the vehicle; and a pair of left and right second connecting parts that movably connect the left beam 17a and the right beam 17b to each other.SELECTED DRAWING: Figure 1
【課題】クロスビームの捩れ量と、トレーリングアームの変位量との両者を調和すること。【解決手段】左右一対のハブキャリア14a、14bは、後輪の車軸Aよりも車両後方で車幅方向且つ車両内側方向に延びる前腕部30と、前腕部30よりも車両後方に延びる後腕部32とを有し、車両前後方向に延びるトレーリングアーム12a、12bの車両後方端部25を、ラテラルビーム16と結合する左右一対の第3ブッシュ26a、26bである第1結合部を設け、ラテラルビーム16は、車両左側に配置されたハブキャリア14aから車幅方向内側に延びる左ビーム17aと、車両右側に配置されたハブキャリア14bから車幅方向内側に延びる右ビーム17bと、左ビーム17a、右ビーム17b同士を変位可能に結合する左右一対の第2結合部とを有する。【選択図】図1
