PROBLEM TO BE SOLVED: To provide a floor structure under a dust-outlet part capable of more effectively fixing a floor panel to a continuous footing and having good workability. SOLUTION: A cutout part A is provided on the end part of the floor panel 3, a fixing metal fitting 5 is mounted on the upper surface thereof, and an anchor bolt 2 is fastened, whereby the fastening axial force presses down the floor panel 3 through the fixing metal fitting 5. The cutout part A is provided widely in the longitudinal direction of the end of the floor panel 3 to set the setting surface of the fixing metal fitting 5 wide, whereby the fastening axial force is more extensively transmitted with a good balance to effectively fix the floor panel 3 to the continuous footing 1 without deflection. The workability in fastening can be also improved by extending the cutout part A.
