To provide a trailing arm structure that reduces vibration transmitted from an in-wheel motor to a vehicle body via a trailing arm.SOLUTION: The trailing arm structure includes an in-wheel motor drive device 10 arranged in an inner space area of the road wheel W, a trailing arm 40 extending in the vehicle longitudinal direction and having a front end 42 swingably connected to a vehicle body-side member via a bush 44 and a rear end 41 coupled to the in-wheel motor drive device 10, and a spring 50 which is vertically expandable and contractable, in which the lower end is supported by the in-wheel motor drive device 10 and the upper end supports the vehicle body 70 and expands and contracts with the swing of the trailing arm 40. The position of the spring 50 in the vehicle longitudinal direction overlaps with the position of the axis O representing the axle in the vehicle longitudinal direction.SELECTED DRAWING: Figure 2

    【課題】インホイールモータからトレーリングアームを経由して車体に伝達する振動を少なくするトレーリングアーム構造を提供する。【解決手段】トレーリングアーム構造は、ロードホイールWの内空領域に配置されるインホイールモータ駆動装置10と、車両前後方向に延び前方端42がブッシュ44を介して車体側メンバに揺動可能に連結され、後方端41がインホイールモータ駆動装置10と結合するトレーリングアーム40と、上下方向に伸縮可能であって下端がインホイールモータ駆動装置10に支持され上端が車体70を支持しトレーリングアーム40の揺動に伴って伸縮するスプリング50とを備え、スプリング50の車両前後方向位置が、車軸を表す軸線Oの車両前後方向位置と重なる。【選択図】図2
