PROBLEM TO BE SOLVED: To provide a floor-panel height-increasing supporting device, by which space height under a floor panel can be increased without removing an existing supporting device and generating an unnecessary part by utilizing the supporting device, in which the labor of preassembly is slight when space height under the floor panel may low, and dynamic reinforcement corresponding to height increase is executed easily. SOLUTION: In the floor-panel height-increasing supporting device, a height increasing member 14 with a cylindrical section 15, an upper supporting section 16 fixed at the upper end of the cylindrical section, a top-section screw rod 17 disposed in upright at the upper side of the upper supporting section and a downward female screw section 18 screwed towards a lower section in the upper supporting section is interposed between the bottom-section supporting member 1 of the floor panel supporting device for low-reference space height and a panel receiving member 6.
