## Abstract

A motor vehicle includes a front side member disposed on each of opposite lateral sides in a front portion of a vehicle, and a crash box disposed forward of the front side member. The crash box extends further outward in a vehicle width direction with respect to the front side member. The motor vehicle further includes a triangular gusset attached to the front side member and the crash box. The triangular gusset includes an oblique portion extending diagonally forward from where the triangular gusset is joined to the front side member. A reinforcing patch is further disposed close to the triangular gusset along the oblique portion of the triangular gusset. This vehicle structure enables transmission to the front side member of a load input to the gusset, which is greater than an assumed load.

## Claims

### Claim 1

A vehicle front structure, comprising:
a front side member disposed on each of opposite lateral sides in a front portion of a vehicle;
a load transmission member disposed forward of the front side member, the load transmission member including a wide portion extending further outward with respect to the front side member and transmitting rearward a load applied from forward;
a gusset having a rear end attached to an outer side face of the front side member, the gusset having an oblique portion extending forward and outward from the rear end, the oblique portion having a front end that is attached to a rear face of the wide portion of the load transmission members; and
a reinforcement attached to the oblique portion of the gusset, the reinforcement having a shape extending from a vicinity of the rear end toward a front end of the gusset.

### Claim 2 (depends on 1)

The vehicle front structure according to claim 1, further comprising:
a side-member-side-member load transmission member disposed inward of the front side members on the opposite lateral sides, the side-member-side-member load transmission member being configured to transmit a load between the front side members, wherein
the side-member-side-member load transmission member includes, on faces opposite the respective front side members, recessed portions each extending along a vehicle height and being disposed further rearward with respect to a portion of the front side member where the rear end of the gussets is attached.

### Claim 3 (depends on 1)

The vehicle front structure according to claim 1, wherein
the reinforcement comprises a three-dimensional combination of at least two plates.
