Abstract: A floor cross member is joined to an upper surface of a floor panel so as to traverse a raised tunnel portion of the floor panel. The floor cross member is composed of a cross member center component formed of an aluminum alloy cast and cross member side components formed of steel plates and arranged on left and right sides of the cross member center component, respectively. A recess is formed in an undersurface of the cross member center component to evade the tunnel portion. Upper plates of the left and right cross member side components are placed at the same height position as a base plate of the cross member center component, and an end of each of the upper plates of the left and right cross member side components contacts with a contact surface of the base plate of the cross member center component.
