To provide a doorway structure that is able to prevent pinching by a door without contact with an obstacle.SOLUTION: A doorway structure comprises: an electric slide door 12 that opens/closes a door opening 26 for a doorway provided in a vehicle body and includes a door lower portion 38 opposite in a vehicle vertical direction to a vehicle floor portion 24 in a door closed state; and a piezoelectric sensor 68 provided at a position opposite to the door lower portion 38 in the vehicle floor portion 24 and detects the self-weight of an occupant and inhibits a closing operation of the electric slide door 12. When the self-weight of an occupant is detected by the piezoelectric sensor 68 in a door open state, a closing operation of the electric slide door 12 is inhibited, and, therefore, a state of the doorway can be detected before the start of a closing operation, without affecting an opening operation of the door. Accordingly, unlike a conventional system, pinching by the door can be prevented without contact with an obstacle.SELECTED DRAWING: Figure 2

    【課題】障害物に接触することなく扉による挟み込みを防止することのできる乗降口構造を得る。【解決手段】乗降口構造は、車体に設けられた乗降用のドア開口部26を開閉すると共に、ドア閉状態において車両フロア部24と車両上下方向に対向するドア下部38を備えた電動スライドドア12と、車両フロア部24におけるドア下部38との対向位置に設けられ、乗員の自重を検知して電動スライドドア12の閉動作を禁止させる圧電センサ68と、を有する。ドア開状態時に、圧電センサ68によって乗員の自重が検知されると、電動スライドドア12の閉動作が禁止されるため、扉の開作動に影響することなく閉作動開始前に乗降口の状況を検知することができ、従来のシステムのように障害物に接触することなく扉による挟み込みを防止することができる。【選択図】図2
