## Abstract

A suspension member includes a cross member and front body mounts. The cross member includes a main panel including a lower panel and an upper panel joined together, and a reinforcing panel joined to the main panel. The cross member is a member including a front wall, an upper wall, a rear wall, and a lower wall, and having a closed sectional shape defined by the front wall, the upper wall, the rear wall, and the lower wall. The reinforcing panel includes a lower flange constituting a front portion of the lower wall, and an intermediate wall extending upward from a rear end of the lower flange and joined to the upper wall. On opposite sides of the cross member in a vehicle-width direction, bottom walls of the front body mounts are joined to the flange, and side walls of the front body mounts are joined to the main panel.
