Vehicle door

摘要

A vehicle door includes a door body, a lower reinforcing member extending in a door width direction at a lower end inside the door body, and a door beam including a beam extension portion extending downwards from a beam body portion extending in the door width direction. The lower reinforcing member includes an upper surface extending in a substantially horizontal direction and an outer side surface extending downwards from the upper surface. The upper surface includes a concave portion and a convex portion. The beam extension portion includes an extension portion body disposed so as to overlap the outer side surface from the vehicle outer side when viewed in a vehicle inside-outside direction, and an inner extension portion that extends towards a vehicle inner side from the extension portion body and that is disposed so as to overlap the convex portion when viewed in the door width direction.

主权项

1. A vehicle door, comprising:
