1. A gap hiding structure for a vehicle luggage floor comprising:

a gap hiding board hinged to the vehicle luggage floor and configured to cover a gap between the luggage floor and a seat installed on a front side of the luggage floor;

a rear tilt down mechanism configured to cause the entire seat to be sunk from a use position where the seat is used as a seating part to an underfloor storage position where the seat enters a lower side of the gap hiding board with a forward tilting of a seat back;

a support part configured to come into contact with and support the gap hiding board, the support part including:

a first support surface portion which forms a substantially horizontal plane, and which is configured to come into contact with the gap hiding board from the lower side of the gap hiding board and support the gap hiding board to be substantially flush with the luggage floor in a state where the seat is in the use position; and

a second support surface portion which is provided at a rear surface portion of the seat back, wherein when the seat is in the use position, the second support surface portion forms a standing surface, and when the seat is in the underfloor storage position, the second support surface portion forms a substantially horizontal plane, is configured to come into contact with the gap hiding board from the lower side of the gap hiding board and support the gap hiding board to be substantially flush with the luggage floor; and

a lifting mechanism configured to push up the gap hiding board to a high position at which the gap hiding board is capable of avoiding interference with the second support surface portion by bringing the first support surface portion close to a rotation center of the gap hiding board while lifting the first support surface portion in a substantially horizontal manner according to a rearward movement of the seat toward the underfloor storage position.

2. The gap hiding structure for the vehicle luggage floor according to claim 1 ,

wherein the first support surface portion is an overhang portion protruding to a rear side of a seat cushion of the seat, and

wherein a rear upper corner portion of the overhang portion is configured to come into contact with the gap hiding board and push up the gap hiding board to the high position according to the rearward movement of the seat toward the underfloor storage position.

3. The gap hiding structure for the vehicle luggage floor according to claim 2 ,

wherein the first support surface portion is configured to push up the gap hiding board to the high position according to the rearward movement of the seat toward the underfloor storage position, and then, a contact state of the first support surface portion with the gap hiding board is separated downward in a region at a front side of the rotation center of the gap hiding board.

4. The gap hiding structure for the vehicle luggage floor according to claim 1 ,

wherein the second support surface portion is disposed at a position higher than the first support surface portion when the seat is in the underfloor storage position.

5. The gap hiding structure for the vehicle luggage floor according to claim 1 ,

wherein the rear tilt down mechanism includes a rear link rotatably connected to the seat cushion and an underfloor surface of the vehicle,

wherein the rear link is in a first position forwardly tilted when the seat is in the use position, in a second position that is in standing posture when the seat moves rearward toward the underfloor storage position, and in a third position rearwardly tilted when the seat is in the underfloor storage position, and

wherein the lifting mechanism is configured by the rear tilt down mechanism having a configuration that is configured to move the first support surface rearward while raising the first support surface by rotating and lifting the rear link from the first position to the second position.
