Problems solved by technology

[0008] In addition, although it is also conceivable to form the floor under the floor other than the passage part flatly without providing an under cover, if a member connecting both ends of the floor passage is provided, such a connecting member will be difficult to install from the viewpoint of installability. The structure connected under the floor on both sides of the aisle, so it is located below the floor surface, and there is still a problem with the minimum ground clearance

Abstract

There is provided a lower vehicle-body structure that allows miniaturization of an undercover and prevents an increase in minimum ground clearance. In the lower vehicle-body structure, a vehicle bodyfloor 2 includes step-up portions 48 connected to a floor tunnel 50 on opposite sides of the floor tunnel 50 in a vehicle width direction at least in regions where first and second cross members 14, 16 are disposed on the vehicle body floor 2. The lower vehicle-body structure includes a mount member 70 that faces the floor tunnel 50 and connects the step-up portions 48 on the opposite sides of thefloor tunnel 50, and includes first and second under covers 102, 104 that cover a lower side of the mount member 70 so as to be continuous with a bottom surface of the vehicle body floor 2 on outer sides of the step-up portions 48 in the vehicle width direction.

Description

technical field [0001] The present invention relates to the underbody structure of a vehicle, and more particularly to an underbody structure with a center tunnel. Background technique [0002] In vehicles such as FR (Front Rear Drive) and 4WD (Four Wheel Drive) vehicles, a propeller shaft extending in the vehicle front-rear direction is provided on a power transmission path from a drive source to drive wheels. The propeller shaft is usually arranged in a floor tunnel provided at the center of the vehicle body floor in the vehicle width direction. In addition, for example, in a vehicle equipped with a so-called longitudinally mounted powertrain, at least a part of the transmission may be disposed in the floor tunnel. [0003] In order to improve the aerodynamic performance of the vehicle, an under cover is provided under the floor to rectify the airflow passing under the floor when the vehicle is running. [0004] For example, Patent Document 1 discloses an undercover for ...
