To reduce a wall thickness of a hub attachment part, and to achieve weight reduction while securing the toe rigidity and the camber rigidity of the hub attachment part, and the internal quality of the hub attachment part.SOLUTION: In trailing arms 3 arranged at left-and-right both sides of a vehicle width direction, and each having at least a hub attachment part 32, a spring attachment part 33 and an absorber attachment part 34, the trailing arm has: a first connecting part 35 extending toward the spring attachment part 33 and the absorber attachment part 34 from a vehicle upper side of the hub attachment part 32A, and connecting the hub attachment part 32A, the spring attachment part 33 and the absorber attachment part 34 to one another; and a second connecting part 36 extending toward the spring attachment part 33 from a vehicle lower side of the hub attachment part 32A, and connecting the hub attachment part 32A and the spring attachment part 33 to each other. In a point located at least at the hub attachment part 32A side, the first connecting part 35 and the second connecting part 36 are separated from each other.SELECTED DRAWING: Figure 4

    【課題】ハブ取付部のトー剛性及びキャンバー剛性とハブ取付部の内部品質を確保しながら、ハブ取付部の肉厚を低減させ、軽量化を実現することにある。【解決手段】車両幅方向の左右両側に配置され、少なくともハブ取付部32とスプリング取付部33とアブソーバ取付部34を有するトレリングアーム3において、ハブ取付部32Aの車両上側からスプリング取付部33及びアブソーバ取付部34に向かって延び、ハブ取付部32Aとスプリング取付部33及びアブソーバ取付部34とを連結する第1の連結部35を有するとともに、ハブ取付部32Aの車両下側からスプリング取付部33に向かって延び、ハブ取付部32Aとスプリング取付部33とを連結する第2の連結部36を有し、少なくともハブ取付部32A側に位置する箇所では、第1の連結部35と第2の連結部36とが離間して配置されている。【選択図】図4
