BOARDING/ALIGHTING PORT FLOOR STRUCTURE OF VEHICLE

PROBLEM TO BE SOLVED: To provide a floor structure capable of avoiding the generation of a step height being a hindrance to boarding/alighting at the indoor side of a boarding/alighting port. SOLUTION: The boarding/alighting port 14 is formed at a side of a vehicle. A passage floor surface 21 existing in a higher position than a lower frame of the boarding/alighting port 14 is formed at the vehicle inside. A first slope member 40 is arranged at a floor 20 of the boarding/alighting port 14. The first slope member 40 extends in an upper gradient of an inclination of 5 degrees or smaller toward the center in the vehicle width direction of the passage floor surface 21 from the lower frame of the boarding/alighting port 14. A second slope member 50A is arranged between the side edge 40b in the vehicle width direction of the first slope member 40 and the passage floor surface 21. The second slope member 50A has a first connecting part 61 continuing with the side edge 40b of the first slope member 40 and a circular arc-shaped second connecting part 62 continuing with the passage floor surface 21. The second slope member 50A has an inclined face 63 inclined in an upper gradient of an upper gradient or smaller of the first slope member 40 toward the second connecting part 62 from the first connecting part 61.
