To provide a technology that improves rigidity of an attachment portion of a trailing arm.SOLUTION: A trailing arm attachment structure includes: a rear member extending in a vehicle fore and aft direction and having an attachment portion to which a trailing arm is attached; and a reinforcement member which is disposed overlapping with the rear member in at least the attachment portion. The rear member and the reinforcement member define at least a part of a reinforcement part. The reinforcement part has a cylindrical shape extending in the vehicle fore and aft direction. A cross section, which is perpendicular to the vehicle fore and aft direction, of the cylindrical shape has a closed cross section in at least a part as seen in the vehicle fore and aft direction.SELECTED DRAWING: Figure 3
