Abstract

A vehicle body front section structure has a floor tunnel that projects into a vehicle interior on an underfloor of a vehicle, that is formed in a vehicle longitudinal direction, and that has a floor tunnel front end part disposed at a vehicle front of the floor tunnel, and floor tunnel members, a front end ridge line part, a first vehicle body front section reinforcing member that covers, from an outside of the vehicle, a whole of the floor tunnel front end part, from a vehicle upper end to a root of each of the floor tunnel members, and that is provided in the vehicle longitudinal direction along the front end ridge line part, and front side members, each of which has a lower end root that is connected to a dash panel, and each of which extends forward from the lower end root.

First claim

The invention claimed is:

1. A vehicle body front section structure, comprising:
a floor tunnel that projects into a vehicle interior on an underfloor of a vehicle, that is formed in a vehicle longitudinal direction, and that comprises:
a floor tunnel front end part disposed at a vehicle front of the vehicle tunnel, and floor tunnel members;

a front end ridge line part;
a first vehicle body front section reinforcing member that covers, from an outside of the vehicle, a whole of the floor tunnel front end part, from a vehicle upper end to a root of each of the floor tunnel members, and that is provided in the vehicle longitudinal direction along the front end ridge line part;
front side members, each of which comprises a lower end root that is connected to a dash panel, and each of which extends forward from the lower end root; and
a second vehicle body front section reinforcing member that couples the first vehicle body front section reinforcing member to the lower end root of the front side member.

2. The vehicle body front section structure according to claim 1 ,
wherein the first vehicle body front section reinforcing member is connected to the floor tunnel member.

3. The vehicle body front section structure according to claim 1 , comprising:
a third vehicle body front section reinforcing member that continuously couples a vicinity of the lower end root of each of the front side members to a dash side panel part.

4. The vehicle body front section structure according to claim 1 , comprising:
a fourth vehicle body front section reinforcing member that continuously couples the lower end root of each of the front side members to a vehicle front end part of a side sill.

5. The vehicle body front section structure according to claim 1 , comprising:
a fourth vehicle body front section reinforcing member that continuously couples a vehicle interior on-floor member provided in accordance with the lower end root of each of the front side members to a vehicle front end part of a side sill.

6. The vehicle body front section structure according to claim 2 , comprising:
a third vehicle body front section reinforcing member that continuously couples a vicinity of the lower end root of each of the front side members to a dash side panel part.

7. The vehicle body front section structure according to claim 2 , comprising:
a fourth vehicle body front section reinforcing member that continuously couples the lower end root of each of the front side members to a vehicle front end part of a side sill.

8. The vehicle body front section structure according to claim 3 , comprising:
a fourth vehicle body front section reinforcing member that continuously couples the lower end root of each of the front side members to a vehicle front end part of a side sill.

9. The vehicle body front section structure according to claim 2 , comprising:
a fourth vehicle body front section reinforcing member that continuously couples a vehicle interior on-floor member provided in accordance with the lower end root of each of the front side members to a vehicle front end part of a side sill.

10. The vehicle body front section structure according to claim 3 , comprising:
a fourth vehicle body front section reinforcing member that continuously couples a vehicle interior on-floor member provided in accordance with the lower end root of each of the front side members to a vehicle front end part of a side sill.

11. The vehicle body front section structure according to claim 4 , comprising:
a fourth vehicle body front section reinforcing member that continuously couples a vehicle interior on-floor member provided in accordance with the lower end root of each of the front side members to a vehicle front end part of a side sill.
