<P>PROBLEM TO BE SOLVED: To provide a double-floor structure which can prevent the loss of a closure used for blocking a retrieving outlet of wiring, which can eliminate the need for storage of the closure of the retrieving outlet from which the wiring has been retrieved, and which can prevent the closure from becoming detached from the retrieving outlet of the wiring. Ž<P>SOLUTION: The double floor structure is constituted by supporting a plurality of flooring panels on a foundation floor surface at a predetermined height. A wiring-pull out recess 54 is formed on a wiring-pull out panel 50 which is one of the plurality of flooring panels, and the wiring-pull out recess 54 connects between a first space which is below the plurality of flooring panels and a second space which is above the plurality of flooring panels. Then the closure 64, which can block the wiring pull out recess 54 of the wiring-pull out panel 50, is integrally provided to a blocking panel 60 which is adjacent to the wiring-pull out panel 50. The wiring-pull out recess 54 can be opened and closed by the closure 64 by turning and arranging at least either the wiring-pull out panel 50 or the blocking panel 60 to change direction.
