## Abstract

A front portion structure of a vehicle includes a front bumper R/F, a side member, and a crush box inserted between the front bumper R/F and the side member, the side member having a first region connected to the crush box and a second region extending from a rear end of the first region, in which a vehicle-widthwise outer side surface of the first region is at a position being bent with respect to a vehicle-widthwise outer side surface of the crush box so as to form a protrusion protruding vehicle-widthwise outward, and a vehicle-widthwise outer side surface of the second region is at a position being bent from the vehicle-widthwise outer side surface of the first region so as to form a protrusion protruding vehicle-widthwise inward, and a reinforcement plate is joined to the vehicle-widthwise outer side surface in the first region.

## Claims

### Claim 1

A front portion structure of a vehicle, comprising:
a front bumper reinforcement extending along a vehicle width direction;
a side member disposed rearward of the front bumper reinforcement in the vehicle so as to extend along a vehicle longitudinal direction; and
a crush box disposed between the front bumper reinforcement and the side member; wherein
the side member has a first region connected to the crush box and a second region extending from a rear end of the first region;
a vehicle-widthwise outer side surface of the side member in the first region is arranged at a position being bent with respect to a vehicle-widthwise outer side surface of the crush box so as to form a protrusion protruding outward in the vehicle width direction;
a vehicle-widthwise outer side surface of the side member in the second region is arranged at a position being bent with respect to the vehicle-widthwise outer side surface in the first region so as to form another protrusion protruding inward in the vehicle width direction, and
a reinforcement plate is attached to the vehicle-widthwise outer side surface in the first region.

### Claim 2 (depends on 1)

The front portion structure of a vehicle according to claim 1, wherein an angle of inclination of the vehicle-widthwise outer side surface in the first region relative to the vehicle longitudinal direction is greater than an angle of inclination of the vehicle-widthwise outer side surface of the crush box relative to the vehicle longitudinal direction.

### Claim 3 (depends on 1)

The front portion structure of a vehicle according to claim 1, wherein:
the crush box is connected via a joint portion to the side member, and
the joint portion is integrally formed with the crush box so as to extend from a rear end of the crush box, and is joined to an interior peripheral surface of the side member.

### Claim 4 (depends on 1)

The front portion structure of a vehicle according to claim 1, wherein the reinforcement plate is formed in a shape that covers substantially an entire area of the vehicle-widthwise outer side surface in the first region.

### Claim 5 (depends on 1)

The front portion structure of a vehicle according to claim 1, wherein a front end of the reinforcement plate is equipped with a gusset portion protruding outward in the vehicle width direction.
