PROBLEM TO BE SOLVED: To provide a double-floor support device, applicable to a double-floor of a multiple dwelling house such as an apartment, coping with heavy impact sound and light impact sound in a simple mechanism to remarkably reduce the manufacturing cost, adjusting the level without repairing uneveness of the floor, and used in the end of a floor joist. SOLUTION: This double-floor support device is placed on a horizontal concrete slab 6 to support a floor panel 5 forming a bed of a floor thereon. The device includes: an elongated horizontal elastic member 21 extended horizontally; a support leg part 22 for supporting both end parts of the horizontal elastic member on the concrete slab; and a vertical load receiving mechanism 24 for receiving downward load from the floor panel and transmitting the same to the central part of the horizontal elastic member. The vertical load receiving mechanism is horizontally rotated round the vertical axis, thereby variably adjusting the height from the floor panel support part to the upper surface of the concrete slab.
