The function additional floor part 6 is formed like a recess from a general floor boundary and configured to accommodate a frame body 7 supporting the functional member 5. The frame body 7 surrounding the peripheral edge of a recess 61 is installed in the floor part 6 with the recess. The frame body 7 is configured to have a seat part supported by the bottom face of the recess 61 and rise-up parts 72c, 73c rising up from the outer ends of the seat part. The upper ends of the rise-up parts 72c, 73c are arranged at a boundary between the general floor 3 and the floor part 6 with the recess, and a filling layer 62 is formed by filling a filler in a range from the rise-up parts 72c, 73c to a peripheral wall of an embedded object 5. |
