## Abstract

A vehicle body structure includes a bumper beam extending in a vehicle width direction, and a pair of right and left bumper beam mounting members each disposed at an outer side in the vehicle width direction of a back face of the bumper beam and mounting the bumper beam on a front side frame. The bumper beam includes a first displacement promoting part that is provided at a mounting part for the bumper beam and the bumper beam mounting members and capable of promoting displacement of the bumper beam by a collision load. The bumper beam mounting member includes a second displacement promoting part that is provided at the mounting part and capable of promoting displacement of the bumper beam by a collision load.

## Claims

### Claim 1

A vehicle body structure comprising:
a bumper beam extending in a vehicle width direction; and
a pair of right and left bumper beam mounting members each disposed at an outer side in the vehicle width direction of a back face of the bumper beam and mounting the bumper beam on a vehicle body; wherein
at least one of the bumper beam and the bumper beam mounting members includes a displacement promoting part that is provided at a mounting part for the bumper beam and the bumper beam mounting members and capable of promoting displacement of the bumper beam by a collision load.

### Claim 2 (depends on 1)

The vehicle body structure according to claim 1, wherein
the displacement promoting part includes a first displacement promoting part provided in the bumper beam, the first displacement promoting part having a through-hole vertically penetrating the bumper beam, and
the through-hole has an opening width that expands toward an inner side in a front-rear direction of the vehicle planar view.

### Claim 3 (depends on 2)

The vehicle body structure according to claim 2, wherein
the mounting part is provided with a plurality of mounting holes through each of which a mounting member for mounting of the bumper beam and the bumper beam mounting member is inserted, and which are mutually provided at a given interval in the vehicle width direction, and
the first displacement promoting part is provided between adjacent mounting holes of the plurality of mounting holes.

### Claim 4 (depends on 1)

The vehicle body structure according to claim 1, wherein
the mounting part is provided with at least one mounting hole through which a mounting member for mounting of the bumper beam and the bumper beam mounting member is inserted;
the bumper beam mounting member is provided with an extending part that is provided to extend to at least one of upper and lower faces of the bumper beam; and
the displacement promoting part includes a second displacement promoting part provided in the bumper beam mounting member, the second displacement promoting part having a long hole that is formed in the extending part and extends in a front-rear direction of the vehicle, the long hole composing the mounting hole.

### Claim 5 (depends on 4)

The vehicle body structure according to claim 4, wherein
the at least one mounting hole includes a plurality of mounting holes that are mutually provided at a given interval in the vehicle width direction, and
the long hole composes one mounting hole among the plurality of mounting holes, which is located at an inner side in the vehicle width direction.

### Claim 6 (depends on 2)

The vehicle body structure according to claim 2, wherein
the mounting part is provided with at least one mounting hole through which a mounting member for mounting of the bumper beam and the bumper beam mounting member is inserted;
the bumper beam mounting member is provided with an extending part that is provided to extend to at least one of upper and lower faces of the bumper beam; and
the displacement promoting part includes a second displacement promoting part provided in the bumper beam mounting member, the second displacement promoting part having a long hole that is formed in the extending part and extends in a front-rear direction of the vehicle, the long hole composing the mounting hole.

### Claim 7 (depends on 6)

The vehicle body structure according to claim 6, wherein
the at least one mounting hole includes a plurality of mounting holes that are mutually provided at a given interval in the vehicle width direction, and
the long hole composes one mounting hole among the plurality of mounting holes, which is located at an inner side in the vehicle width direction.
