VEHICLE ENTRANCE STRUCTURE

An entrance is provided in a side surface of a body of a vehicle. A side portion of the entrance in the width direction is constituted by a first frame member extending in the vehicle up-down direction. A lower end portion of the entrance is constituted by a floor extension portion of a floor member disposed on the inner side of the entrance with respect to the first frame member. The entrance is provided with a joint member. The joint member extends from the floor extension portion of the floor member to the first frame member, and closes a gap provided between the floor member and the first frame member. Thus, it is possible to suppress wind, rain, noise, etc. from entering a vehicle cabin through the gap.
