Abstract
The support stiffness of a suspension supporting portion can be improved to reduce floor vibration. Arm front-end supporting portions, each supporting a front end portion of a trailing of a rear suspension, are formed on lower portions of rear frames extending in a vehicle longitudinal direction, and each include a squared U-shape portion including outer, inner and front wall portions, with a rear side being open when viewed from the bottom, and an extending outer wall portion extending from the outer wall portion to in front of the front wall portion. The outer wall portion and extending outer wall portion are formed by a side sill inner portion joined to each rear side frame. Also, each arm front-end supporting portion includes an extending inner wall portion extending from the inner wall portion to in front of the front wall portion and joined to each of the rear side frames.
