## Abstract

A hood inner panel (5) includes an inner panel main body (5a) forming part of a hood (1) of a vehicle, a front bead (7) provided on the inner panel main body (5a) and extending along a vehicle width direction, and a rear bead (9) provided on the inner panel main body (5a), located on the rear side of the front bead (7) toward a back of the vehicle and extending along the vehicle width direction. The front bead (7) is curved toward the front of the vehicle such that a center portion (7a) in the vehicle width direction is located in front of each end portion (7b) in the vehicle width direction, and the rear bead (9) is curved toward the back of the vehicle such that a center portion (9a) in the vehicle width direction is located behind each end portion (9b) in the vehicle width direction.

## Claims

### Claim 1

A hood inner panel, comprising:
an inner panel main body forming part of a hood of a vehicle;
a front bead provided on the inner panel main body and extending along a vehicle width direction, the front bead having a center portion in the vehicle width direction and end portions in the vehicle width direction; and
a rear bead provided on the inner panel main body, located toward a rear side of the front bead and extending along the vehicle width direction, the rear bead having a center portion in the vehicle width direction and end portions in the vehicle width direction,
the front bead being curved toward a front of the vehicle such that the center portion of the front bead is located in front of each end portion, and the rear bead being curved toward a back of the vehicle such that the center portion of the rear bead is located behind each end portion,
the front bead being an independent bead unconnected to beads other than the front bead, and
the rear bead being an independent bead unconnected to beads other than the rear bead.

### Claim 2 (depends on 1)

The hood inner panel according to claim 1, wherein an intermediate bead is provided between the front bead and the rear bead and extends in the vehicle width direction.

### Claim 3 (depends on 1)

The hood inner panel according to claim 1, wherein at least one of the front bead and the rear bead has a width in a front-back direction of the vehicle at each end portion that is greater than a width in the front-back direction of the vehicle at the center portion.

### Claim 4 (depends on 1)

The hood inner panel according to claim 1, wherein a radius of curvature R1 of a curved portion on a front side of the front bead and a radius of curvature R2 of a curved portion on a front side of the rear bead satisfy the following expression (1):
R1>R2 (1).

### Claim 5 (depends on 1)

The hood inner panel according to claim 1, wherein a radius of curvature R1 of a curved portion on a front side of the front bead and a radius of curvature R3 of a curved portion on a rear side of the front bead satisfy the following expression:
R1>R3 (2).
