PROBLEM TO BE SOLVED: To provide a flooring load supporting implement less generating noise even when surely locked and used for a long period. SOLUTION: This flooring load supporting implement 1 comprises a base member 10 and a pivotally supporting member 11 pivotally supporting a flooring load. The height of the pivotally supporting member 11 is adjusted between the base member 10 and the pivotally supporting member 11. A post member 13 having a nut receiving part 12 formed integrally with the upper end is vertically formed on the base member 10. A bolt 14 allowing the height of the pivotally supporting member 11 to be adjusted is extended downward from the pivotally supporting member 11. An adjust nut 15 allowing the height of the pivotally supporting member 11 to be changed by screwing onto the bolt 14 and rotating by itself is rotatably fitted to the nut receiving part 12 of the post member 13. A lock nut 17 locking the adjust nut 15 by screwing to a male screw part 16 formed on the outer peripheral surface of the nut receiving part 12 is screwed to the upper side of the bolt 14 more than the adjust nut 15.
