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 lift which changes floor height by vertical movement; a pedestal on which the lift is landed in a storage state where the lift is dropped; a plurality of parallel link members which rockably connect the lift to the pedestal; a widening floor which slides on the lift in the storage state when widening or storing a widening part; a hook which is arranged in a storing direction side of the widening floor; and an engaging part which is arranged in at least one of the parallel link members and engaged with the hook. When widening the widening part, the engaging part is engaged with the hook and the lift is raised up, and when storing the widening part, the engaging part is disengaged from the hook and the lift is landed on the pedestal.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前記床の床高を変化させる昇降部と、前記昇降部が降下した格納状態において前記昇降部が着地する台座部と、前記台座部に前記昇降部を搖動可能に接続する複数の平行リンク部材と、前記拡幅部の拡幅時および収納時において、格納状態の前記昇降部上をスライドする拡幅床と、前記拡幅床の収納方向側に配置されたフックと、少なくとも一つの前記平行リンク部材に設けられ、前記フックと係合する係合部とを備え、前記拡幅部の拡幅の際に前記フックに前記係合部が係合されて前記昇降部が立ち上がり、前記拡幅部の収納の際に前記フックから前記係合部が外れて前記昇降部が前記台座部に着地する。【選択図】図2
