Abstract

A vehicle understructure includes a transaxle including a plurality of enclosures and a fastening part that mutually fastens outer edge parts of the enclosures, an undercover including an interference part that is made of resin, is displaced upward when a road surface interferes with the undercover, and faces the fastening part, and a metal plate that reinforces at least a portion of the interference part.

First claim

What is claimed is:

1. A vehicle understructure comprising:
a transaxle including a plurality of enclosures and a fastening part mutually fastening outer edge parts of the plurality of enclosures, the plurality of enclosures including a housing located on an internal combustion engine side of the transaxle, and a case body located on a case body side of the transaxle opposite to an internal combustion engine, the outer edge parts of the plurality of enclosures include a first flange disposed on an internal combustion engine side of the housing, a second flange disposed on a case body side of the housing, and a third flange formed on the case body, the second flange and the third flange being overlapped with each other and fastened together by the fastening part, the second flange having a lower end that is located nearer to a lower side of a vehicle than a lower end of the first flange when the transaxle is mounted on the vehicle;
an undercover including an interference part made of resin, the undercover configured to be displaced upward upon interference with a road surface, the undercover facing the fastening part; and
a metal plate reinforcing at least a portion of the interference part.

2. The vehicle understructure according to claim 1 , further comprising a shock absorbing material provided between the metal plate and the transaxle, wherein the metal plate is attached to an upper surface of the undercover.

3. The vehicle understructure according to claim 1 , further comprising a mount member elastically supporting the transaxle on a vehicle body, wherein the fastening part is at a lowest position with respect to the vehicle body when the transaxle rocks downward about a supporting position of the mount member.

4. The vehicle understructure according to claim 1 , further comprising a sound absorbing material provided between the metal plate and the transaxle, wherein the metal plate is attached to an upper surface of the undercover.
