Abstract: A vehicle door is provided having an outer panel reinforced by a panel reinforcement and which is configured to generate low-frequency sound dominantly at the time of closing the door. The door has an outer panel openably/closably attached to a vehicle body by a front hinge; and a panel reinforcement extending in a vehicle front-rear direction on an inner side of the outer panel. The outer panel and the panel reinforcement are fixed by plural adhesion sections. The number of the adhesion sections in an upper area of the outer panel is larger than the number of the adhesion sections in a lower area of the outer panel. The number of the adhesion sections provided in a front lower area near the front hinge in the lower area is larger than the number of adhesion sections in a rear lower area away from the front hinge in the lower area.

Abstract: The vehicle door structure includes: a door outer panel including a projected section that projects outward in a vehicle width direction, a recessed section that is separated from the projected section and recessed inward in the vehicle width direction, and a boundary section between the projected section and the recessed section; and a panel reinforcement fixed to an inner surface in the vehicle width direction of the door outer panel. The panel reinforcement includes: a first frame section that extends in a vehicle front-rear direction; and a second frame section at a position that overlaps the boundary section in the vehicle side view and is configured to be able to transmit a load to the first frame section at the time when the load in an inward direction of the vehicle width direction is applied to the boundary section.

Abstract: A side door comprises a door panel portion and a reinforcement portion (a lower-side reinforcement portion and others). The door panel portion is provided to cover an opening portion for entrance and configured such that its peripheral part overlaps with an opening-portion-forming vehicle-body frame member (a side sill and others) in a vehicle side view. The reinforcement portion is provided at the peripheral part of the door panel portion such that it overlaps with the opening-portion-forming vehicle-body frame member in the vehicle side view, thereby reinforcing the peripheral part of the door panel portion against a collision load applied to the side door from a vehicle side. The reinforcement portion is provided at a portion of the peripheral part of the door panel portion which includes a part corresponding to the vehicle-width-direction-extending vehicle-body frame member (a first floor cross member and others).

Abstract: A side door comprises a door panel portion and a reinforcement portion (a rear-side reinforcement portion and others). The reinforcement portion is provided at at least one of a corner portion positioned between a lower portion and a front-side portion of a peripheral part of the door panel portion and another corner portion positioned between the lower portion and a rear-side portion of the peripheral part of the door panel portion such that the reinforcement portion overlaps with a vehicle-body frame member in a vehicle side view. The reinforcement portion is provided with a curved portion at an inside part of the corner portion where the reinforcement portion is provided. The curved portion is configured to be curved convexly toward an outside part of the corner portion in the vehicle side view.
