<p><P>PROBLEM TO BE SOLVED: To adjust the height of floor components 24, 29, 30 by operating either a screw shaft 7 or a female screw member 11 from above. <P>SOLUTION: A floor component support tool 1 includes a shaft body 2 having the screw shaft 7, and an elevation part 3 having the female screw member 11 screwed with the screw shaft 7. A floor component mounting part 12 and a disc spring 13 of the elevation part 3 are pressure-joined by the female screw member 11 in a state being penetrated by a cylindrical part 14 provided on the female screw member 11, but the female screw member 11 can rotate relative to the floor component mounting part 12, and the disc spring 13 makes a braking force act against the rotation of the female screw member 11 relative to the floor component mounting part 12. The height of the floor components 24, 29, 30 can be adjusted either by rotating the shaft body 2 with a screw-side tool fitting part 9 provided in the screw shaft 7 or by rotating the female screw member 11 with a female screw member-side tool fitting part 16 provided in the cylindrical part 14. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
