PROBLEM TO BE SOLVED: To prevent descending of a vehicular door, and to improve door stiffness against a collision load at the time of frontal collision of a vehicle. SOLUTION: At a door front surface portion 21 of a door main body D composed of an outer panel 1 and an inner panel 2 of the vehicular door, a reinforcing member 6 is provided from a door inner side to reinforce. A door hinge 5 is attached to the door front surface portion 21 through the reinforcing member 6, thereby uniting the vehicular door to a vehicle body by the hinge. The reinforcing member 6 and front ends 31, 41 of a door reinforcement 34 extended in a fore-and-aft direction in the inside of the door along a belt line DB of a door main body D. The door front surface portion 21 reinforced by the reinforcing member 6 and the door reinforcements 3, 4 integrally support the weight of the whole of the door. At the time of the front surface collision, the reinforcing member 6 and the door reinforcements 3, 4 integrally receive the collision load. COPYRIGHT: (C)2007,JPO&INPIT
