RESIN BACK DOOR FOR VEHICLE

摘要

A resin back door for a vehicle has: a skeleton portion that structures an opening portion, and that is formed as a closed cross-sectional portion at an interior thereof; and a glass plate supported at the skeleton portion. Each skeleton side portion includes: an inner wall portion structuring an inner peripheral surface of the opening portion; an outer wall portion disposed at a vehicle transverse direction outer side of the inner wall portion; and an intermediate wall portion that is bent toward a vehicle transverse direction outer side and a vehicle outer side from a vehicle outer side end portion of the inner wall portion, and that is joined to a vehicle transverse direction inner side end portion of the outer wall portion. The intermediate wall portion is curved, such that a vehicle transverse direction intermediate portion is convex toward an exterior of the closed cross-sectional portion.

1. A resin back door for a vehicle comprising:
a skeleton portion that structures a frame portion of an opening portion for viewing toward a rear of a vehicle, and that is formed as a closed cross-sectional structure having a closed cross-sectional portion at an interior thereof due to an inner panel and an outer panel that are made of resin being joined together; and a glass plate that is supported at the skeleton portion and closes the opening portion from a vehicle outer side, wherein skeleton side portions that structure vehicle transverse direction side portions at the skeleton portion are each structured to include: an inner wall portion that is disposed such that a plate thickness direction thereof extends in a vehicle transverse direction, and that structures an inner peripheral surface of the opening portion; an outer wall portion that is disposed at a vehicle transverse direction outer side of the inner wall portion and that faces the glass plate; and an intermediate wall portion that is bent toward a vehicle transverse direction outer side and a vehicle outer side from a vehicle outer side end portion of the inner wall portion, and that is joined to a vehicle transverse direction inner side end portion of the outer wall portion, the intermediate wall portion being curved in a cross-section cut in the vehicle transverse direction, such that a vehicle transverse direction intermediate portion is convex toward an exterior of the closed cross-sectional portion.
