Abstract: An under cover for covering a base face of a vehicular body, includes: 1) a dent part; and 2) a protruding part. The dent part and the protruding part are formed alternately in series on a lower face of the under cover in at least a forward-rearward direction of a vehicle. The dent part and the protruding part have a cross section formed into a serial curved face.

Abstract: A vehicle rear body structure including: a cross member provided beneath a rear parcel shelf to connect upper ends of rear suspension towers; a strip member provided along a rear edge of a floor panel; and panel members provided between the cross member and the strip member to connect the cross member and the strip member. The panel members include a center panel and a pair of side panels arranged on outer sides in a vehicle transverse direction of the center panel, respectively. Each of the side panels is joined along an inner edge in the vehicle transverse direction thereof to the center panel by a continuous welding.

Abstract: A rear underside structure of a vehicle as a rear undercover main body, an air flow path, an air intake opening, and an air exhaust opening. The rear undercover main body has an inclined planar part that rises toward the rear of the vehicle, and is disposed further to the rear of than the fuel tank, between the front and rear axles, so as to cover a drive element of the vehicle. The air flow path is disposed between the rear undercover main body and the drive element. The inclined planar part delineates at least a rear part of the air flow path. The air intake opening is disposed further to the front than the drive element, and the air exhaust opening is disposed to the rear of the inclined planar part. Air which flows in from the air intake opening passes through the air flow path, and is exhausted from the exhaust opening.
