To provide a vehicle rear suspension structure which has an existing structure as a basic structure and may be applied to a four-wheel-drive vehicle which is driven by a motor.SOLUTION: A vehicle rear suspension structure 100 includes a torsion beam 1 and a pair of arm units 2L, 2R. Each of the arm units (2L, 2R) includes a trailing arm 21 formed in a cylindrical shape extending in a vehicle fore and aft direction, an end plate 22 which closes a rear side opening of the trailing arm 21, an upper reinforcing member 25, and a lower reinforcing member 26. A shaft insertion hole (a hole) 2a is formed in an inner portion of a rear arm 21e of the trailing arm 21, the upper reinforcing member 25 is joined to the rear arm 21e so as to run along an upper edge portion 2a1 of a peripheral edge portion of the shaft insertion hole 2a, and the lower reinforcing member 26 is joined to the rear arm 21e so as to run along a lower edge portion 2a2 of the peripheral edge portion of the shaft insertion hole 2a.SELECTED DRAWING: Figure 3

    【課題】既存の構造を基本構造として有すると共に、モータ駆動の4WD車に適用され得る車両用リアサスペンション構造を提供する。【解決手段】車両用リアサスペンション構造100はトーションビーム1と一対のアームユニット2L,2Rとを含む。各アームユニット(2L,2R)は、車両前後方向に延びる筒状に形成されたトレーリングアーム21と、トレーリングアーム21の後側開口を塞ぐエンドプレート22と、上補強部材25と、下補強部材26とを有する。トレーリングアーム21の後アーム21eの内側部分に、シャフト挿入孔(孔)2aが形成され、上補強部材25はシャフト挿入孔2aの周縁部のうちの上側縁部2a1に沿うように後アーム21eに接合され、下補強部材26はシャフト挿入孔2aの周縁部のうちの下側縁部2a2に沿うように後アーム21eに接合される。【選択図】図3
