Abstract: A vehicle upper section structure includes a roof side-rail, a roof panel, and a side outer panel. The roof side-rail is provided at a vehicle width direction end of a vehicle upper section. The roof panel is formed from a material having a higher linear expansion coefficient than that of a material of the roof side-rail, and is provided at a vehicle width direction central portion of the vehicle upper section. The side outer panel is formed from a material having a higher linear expansion coefficient than that of the material of the roof side-rail, is provided at an outer side of a vehicle further than the roof side-rail, and includes a first join joined to the roof side-rail and a second join joined to the roof panel. The first join and the second join are separated from each other.

Abstract: A suspension member includes: a pair of left and right front body mounts, each of which has a front side rail part extending in a front-rear direction of a vehicle body, and a cross part extending inward in a vehicle width direction; a front cross member extending in the vehicle width direction, in which both end parts of the front cross member in the vehicle width direction are joined to the cross parts, respectively; and a protective member that extends in the vehicle width direction and covers an entire lower wall of the front cross member, has a jack-up part for a jack to be applied, and is joined to the lower wall of the front cross member, the jack-up part being provided integrally in the protective member.

Abstract: A suspension member includes: a front frame including a front cross member extending in a vehicle width direction; a rear frame at least partially made of light metal and including a rear cross member extending in the vehicle width direction, the rear frame being placed on a vehicle rear side of the front frame and joined to the front frame; and a protective member joined to the rear cross member so as to form a closed section together with the rear cross member.
