However, if the seat back is tilted forward, a step is generated between the upper surface of the seat back and the upper surface of the floor lid, which may make it difficult to use the luggage space that has become wider.

Therefore, an example in which a floor lid can be installed at an upper position has been conventionally proposed. For example,
In the example described in JP-A-34350, the luggage floor board is divided into two parts, a front board and a rear board, and the rear board has a rectangular shape larger than the front board and somewhat shorter in the front-rear width than the left and right width. The front and rear boards are laid side by side on the steps formed on the left and right side walls of the vehicle, and are arranged at the upper position so as to form the same horizontal plane.

[0004] Then, both boards are removed, the front board is set up as a partition wall between the seat and the trunk floor, and the rear board is rotated quarterly horizontally and fitted between the left and right side walls with the short front-to-rear width before and after rotation. It can be placed on the floor panel. In this manner, the luggage floor board is divided into two to form a rectangular rear board, and the front and rear widths and the left and right widths of the rear board are set to predetermined dimensions so that the luggage floor board can be arranged at any position above and below.

When the rear board is arranged at an upper position together with the front board, it forms the same horizontal plane as the upper surface of the seat back which has been tilted forward, thereby forming a large-area easy-to-use trunk floor.
