PROBLEM TO BE SOLVED: To remove an unpleasant feeling to an occupant by thrusting/striking a back face of a seat back by constituting so that the upper surface inclines downward to a front part from a rear part of an automobile in a standing-up state of a sub-floor. SOLUTION: An opening recessed part 22 having the opening upper surface is formed in a luggage floor body 21 so that a sub-floor 23 is housed in the opening recessed part 22. A four-node parallel link is stood up, and since the upper surface of the sub-floor 23 inclines downward to the front part side from the rear part side of an automobile 10, when placing a long size cargo 4 such as a ski, the long size cargo 4 also inclines toward the front part side of the automobile 10. Even if the long size cargo 4 moves at sudden brake time when the automobile 10 travels, a lower end part of a seat back 13a of a front seat 13 or a back face of a seat cushion 13b is struck, but this part does not normally impart an unpleasant feeling to a sitting person since there is a cushion spring and a seat frame.
