Abstract

On the first diagonal, the member is arranged in cooperation with the subframe and the undercover. Further, the cover front-side connection portion and the cover rear-side connection portion are located on or near the first diagonal line. Further, the undercover is provided with a reinforcing portion extending on a second diagonal line which is a diagonal line of a quadrangle having a cover front side connecting portion and a cover rear side connecting portion as a top portion. Therefore, the rigidity of the frame front connecting portion can be increased. In this structure, since it is not necessary to provide an additional component different from the undercover, it is possible to eliminate an increase in the number of components due to the additional component and an occupation of space due to the additional component.

First claim

What is claimed is:

1 . A vehicle front part structure comprising:
a subframe including right and left frame front side connecting portions connected to right and left lower arms, and right and left frame rear side connecting portions located on a vehicle body rear side from the frame front side connecting portions and connected to a shell body; and an undercover disposed at a rear part of the subframe, the undercover including right and left cover front side connecting portions connected to the subframe, and right and left cover rear side connecting portions located on the vehicle body rear side from the cover front side connecting portions and connected to a battery fixedly attached to the subframe, the shell body, or a corresponding shell body, wherein when viewed from a bottom, the undercover is provided including an area on a first diagonal line that is a longer diagonal line among a diagonal line of a quadrangle with the frame front side connecting portions and the frame rear side connecting portions as vertices and a diagonal line of a quadrangle with the frame front side connecting portions and the cover rear side connecting portions as vertices, the cover front side connecting portions and the cover rear side connecting portions are located on the first diagonal line or in a vicinity of the first diagonal line, and the undercover is provided with a reinforcing portion extending on a second diagonal line that is a diagonal line of a quadrangle with the cover front side connecting portions and the cover rear side connecting portions as vertices.

2 . The vehicle front part structure according to claim 1 , wherein:
in the area on the first diagonal line, there are an area portion in which the subframe is provided and an area portion in which the subframe is not provided; and the undercover is provided including the area portion in which the subframe is not provided.

3 . The vehicle front part structure according to claim 1 , wherein:
the undercover is a one-piece configuration; and the reinforcing portion is composed of a bead provided in the undercover.

4 . The vehicle front part structure according to claim 1 , wherein:
the shell body includes a floor panel provided with a tunnel portion extending in a vehicle body front-rear direction at a center portion in a vehicle body width direction, and right and left underreinforcements that extends in the vehicle body front-rear direction at both right and left outer sides of the tunnel portion and that is disposed on a lower side of the floor panel to provide a closed cross-sectional structure with the floor panel to provide a main skeleton of the shell body; and among the frame rear side connecting portions and the cover rear side connecting portions, connecting portions on the first diagonal line are connected to the shell body at a position on right and left sides of the tunnel portion and on a center side in the vehicle body width direction from the right and left underreinforcements, while avoiding a portion providing a skeleton of the shell body.

5 . The vehicle front part structure according to claim 1 , wherein:
the shell body includes a floor panel; the battery is disposed below the floor panel; and the cover rear side connecting portions are connected to the battery.
