[Problem] To provide a structure for a trailing arm mounting section, the structure being capable of providing high rigidity to a trailing arm mounting portion while preventing an increase in the weight of the vehicle and an increase in cost. [Solution] This structure for trailing arm mounting section (mounting section structure (100)) is configured so as to include a side member (110), a side sill (120), and a bracket (130). The lower surface of the side member is located above the lower surface of the side sill and is mounted to the surface of the bracket, which faces the inside of the vehicle. The structure for trailing arm mounting section further includes a reinforcement member (140) straddling and connecting the lower surface of the side member and the lower surface of the side sill. The structure for a trailing arm mounting section is characterized in that, when viewed from the front of the vehicle, the reinforcement member has a flat surface section (142) having a region surrounded by: the lower surface of the side member; a vertical surface of the side sill, the vertical surface facing the inside of the vehicle in the width direction thereof; and a line or an arc which connects an end of the lower surface of the side member, the end facing the inside of the vehicle in the width direction of the vehicle; and the lower end of a vertical surface of the side sill, the vertical surface facing the inside of the vehicle in the width direction thereof.
