To enable an existing lock mechanism to be used for a vehicle in which a hinge point of a rear door is located at the front side of a vehicle body to inhibit increase of costs.SOLUTION: A rear door structure includes: a hinge which rotatably fixes a rear door to a vehicle body at an upper end part; an engagement part 42 provided at the vehicle body side at a lower end of an opening; a latch mechanism body 18 which can engage with an engagement part to lock the rear door in a closed state; and a reinforcement plate 20 fixed to a support part of an inner panel 22 to which the latch mechanism body is attached. An opening is formed at the support part of the inner panel. The reinforcement plate has: a recessed part 24 which is inserted into the opening and expands from an internal space of the rear door enclosed by the inner panel and an outer panel 36 to the outer side; and a joint part which can be joined to the inner panel. The latch mechanism body is attached to a bottom surface of the recessed part, and the bottom surface inclines so that an amount of expansion relative to the support part becomes smaller from the inner panel side to the outer panel side.SELECTED DRAWING: Figure 2

    【課題】後部ドアのヒンジ点が車体の前方側にある車両に対して、既存のロック機構を利用可能にすることで、コスト増加を抑制する。【解決手段】上端部で車体に対して後部ドアを回動可能に固定するヒンジと、開口部の下端で車体側に設けられた係止部42と、係止部に係止して後部ドアを閉じた状態でロック可能なラッチ機構本体18と、ラッチ機構本体が取り付けられるインナパネル22の支持部に固定される補強板20と、を備え、インナパネルの支持部に開口が形成され、補強板は、開口に挿入されてインナパネルとアウタパネル36とに囲まれる後部ドアの内部空間から外側へ膨出する凹部24と、インナパネルに接合可能な接合部と、を有し、ラッチ機構本体は凹部の底面に取り付けられ、底面は、支持部に対してインナパネル側からアウタパネル側に向かうにつれて膨出量が小さくなるように傾斜する。【選択図】図2
