PROBLEM TO BE SOLVED: To provide a reinforcement structure of a resin back door, effectively improving rigidity without inviting an increase in the number of components and an increase in an assemble man hour.SOLUTION: A reinforcement structure includes a back door inner panel 100 which has a back door upper part 110 extending in the vehicle width direction, right and left back door side parts 121 and 122 extending from both sides of the back door upper part to a lower side, and a back door skirt part 130 connected to the bottom edges of the right and left back door side parts, and in which the back door upper part is provided with a pair of right and left hinge attaching parts 111 and 112, and a lock mechanism attaching part 131 is provided in a lower center of the back door skirt part. Beads or ribs 221, 222, 231 and 232 are formed so as to obliquely upward extend from the vicinity of the lock mechanism attaching part, and reach the vicinity of connection parts 151 and 152 between the back door skirt part and the back door side part. The connection part between the back door skirt part and the back door side part has a U-shaped cross section part 210, and the ribs 231 and 232 are connected to the internal surface of the U-shaped cross section part.SELECTED DRAWING: Figure 1
