Abstract

A structure of a vehicle side door includes: an inner panel including a first protrusion and a second protrusion alternately provided in a vehicle front-rear direction at an upper end of the inner pane, the first protrusion protruding to the inner side, the second protrusion protruding to an outer side; an inner reinforcement that has a flange and is provided along the vehicle front-rear direction, the flange including a joint and a cutout alternately provided in the vehicle front-rear direction, the joint being joined to a surface of the first protrusion on the outer side, the cutout exposing the second protrusion from the flange to the outer side; and a weatherstrip provided along the vehicle front-rear direction, the weatherstrip including a pinching part that contacts a surface of the first protrusion on the inner side and a surface of the second protrusion on the outer side.

First claim

What is claimed is:

1. A structure of a side door of a vehicle, the structure comprising:
an inner panel that forms an inner side of the side door in a vehicle width direction of the vehicle, the inner panel including a first protrusion and a second protrusion, the first protrusion and the second protrusion being provided at an upper end of the inner panel in a vehicle upper-lower direction, the first protrusion protruding inwardly with respect to the vehicle width direction, the second protrusion protruding outwardly with respect to the vehicle width direction relative to the first protrusion, the first protrusion and the second protrusion being provided in a vehicle front-rear direction;
an inner reinforcement that has a flange fixed to the upper end of the inner panel and is provided along the vehicle front-rear direction, the flange including a joint and a cutout, the joint being joined to a surface of the first protrusion on an outer side of the side door in the vehicle width direction, the second protrusion protruding farther outward than the flange to the outer side in the vehicle width direction, the joint and the cutout being provided in the vehicle front-rear direction; and
a weatherstrip provided at the upper end of the inner panel along the vehicle front-rear direction, the weatherstrip including a pinching part holding the inner panel by pinching the inner panel in the vehicle width direction in such a manner that the pinching part contacts a surface of the first protrusion on the inner side in the vehicle width direction and a surface of the second protrusion on the outer side of the side door in the vehicle width direction.

2. The structure of the side door according to claim 1 , wherein
the flange includes a third protrusion that is adjacent to the joint, protrudes to the outer side of the side door in the vehicle width direction relative to the joint, and the third protrusion includes the cutout.

3. The structure of the vehicle side door according to claim 1 , further comprising
an outer panel facing an outside of the vehicle, wherein
the inner panel is disposed on the inner side of the side door in the vehicle width direction relative to the outer panel.

4. The structure of the side door according to claim 1 , wherein:
in a cross-sectional view perpendicular to the vehicle upper-lower direction, the first protrusion and the pinching part define a trapezoidal shape protruding to the inner side of the side door in the vehicle width direction relative to the second protrusion; and
in the cross-sectional view perpendicular to the vehicle upper-lower direction, the second protrusion and the pinching part define a trapezoidal shape protruding to the outer side of the side door in the vehicle width direction relative to the first protrusion.

5. The structure of the side door according to claim 2 , wherein
an amount of protrusion of the third protrusion from the joint to the outer side of the side door in the vehicle width direction is smaller than an amount of protrusion of the second protrusion from the surface of the first protrusion on the outer side of the side door in the vehicle width direction.

6. The structure of the side door according to claim 1 , wherein
the pinching part holds the upper end of the inner panel by pressing the surface of the first protrusion on the inner side of the side door in the vehicle width direction from the inner side of the side door in the vehicle width direction and pressing the surface of the second protrusion on the outer side of the side door in the vehicle width direction from the outer side of the side door in the vehicle width direction.
