PROBLEM TO BE SOLVED: To provide a structure of a trailing arm attachment part which can obtain high rigidity even in a trailing arm attachment point while suppressing an increase of the weight and cost of a vehicle.SOLUTION: This structure (attachment part structure 100) of a trailing arm attachment part includes a side member 110, a side sill 120 and a bracket 130. A lower face of the side member is located in an upper part rather than a lower face of the side sill, attached to a side of the bracket at the inside of a vehicle, and includes a reinforcing member 140 which straddles the lower face of the side member and the lower face of the side sill, and connects these lower faces. In a vehicle front view, the reinforcing member has the lower face of the side member, a vertical face of the side sill at the inside of a vehicle width direction, and a plane part 142 having a region which is surrounded by a line component or an arc which connects an end part of the lower face of the side member at the inside of the vehicle width direction and a lower end of the vertical face of the side sill at the inside of the vehicle width direction.

    【課題】車両の重量増大やコストの増大を抑制しつつ、トレーリングアーム取付箇所において高い剛性を得ることが可能なトレーリングアーム取付部構造を提供する。【解決手段】本発明にかかるトレーリングアーム取付部構造(取付部構造100)の構成は、サイドメンバ110と、サイドシル120と、ブラケット130とを含み、サイドメンバの下面は、サイドシルの下面より上方に位置していて、ブラケットの車両内側の面に取り付けられ、サイドメンバの下面とサイドシルの下面とに跨ってそれらを連結する補強部材140を更に含み、補強部材は、車両前方視において、サイドメンバの下面と、サイドシルの車幅方向内側の縦面と、サイドメンバの下面の車幅方向内側の端部からサイドシルの車幅方向内側の縦面の下端までを結ぶ線分または弧とによって囲まれた領域を有する平面部142を有することを特徴とする。【選択図】図3
