To provide a floor lifting mechanism capable of easily improving safety in a vehicle body when a widening part is widened.SOLUTION: A floor lifting mechanism comprises: a floor part which changes floor height by vertical movement; a pedestal which is fixed in a vehicle body; a plurality of parallel link members which rockably connect the floor part to the pedestal; and an energization member which energizes the floor part upward at all times. A plane member is arranged in the parallel link member in which a plane part of the plane member becomes parallel with the floor part when the floor part is dropped, and a contact part contacting with the plane part is arranged at the lower edge in the storing direction of a widening part. When the widening part is moved in the storing direction and the widening direction in a state where the contact part contacts with the plane part, an inclination angle of the parallel link member in accompany with behavior of the floor part changes depending on position of the contact part.SELECTED DRAWING: Figure 2

    【課題】拡幅部を拡幅した場合において、容易に車体内の安全性を向上させることができる床昇降機構を提供する。【解決手段】昇降することにより床高を変化させる床面部と、車体内部に固定された台座部と、前記台座部に前記床面部を搖動可能に接続する複数の平行リンク部材と、前記床面部を常時上側に付勢する付勢部材とを備え、前記平行リンク部材には、前記床面部が降下した状態において、前記床面と平行になる平面部を有する平面部材が配置され、前記拡幅部の収納方向側の下端には前記平面部と当接する当接部が設けられ、前記当接部と前記平面部が当接した状態で前記拡幅部が前記収納方向または前記拡幅方向に移動する際に、前記当接部の位置によって、前記床面部の挙動に伴う前記平行リンク部材の傾斜角度が変化する。【選択図】図2
