According to a fifth aspect of the present invention, there is provided a base member having a support bolt projecting from a base plate, a nut member screwed to the support bolt of the base member, and an upper portion of the support bolt in an insertion hole. It has a floor panel receiving member that is inserted and arranged, and the lower part is placed on a nut member and is installed on the upper part of the support bolt body, and the support bolt body is formed into a polygonal cross section threaded on the outer peripheral surface and inserted A second connecting means for forming the cross-sectional shape of the hole into a polygonal shape that matches the cross-sectional shape of the support bolt body, restricting horizontal rotation with respect to the support bolt body, and connecting the nut member to the floor panel receiving member. Therefore, when connecting each part while preventing the parts from rotating, there is no need to align the concave groove and the engaging protrusion to engage the concave groove and the engaging protrusion. Insert the upper part of the body In this way, the floor panel receiving member and the support bolt body can be connected to each other while preventing rotation, and the cylindrical body and the insertion section can be connected to each other while preventing rotation by inserting the insertion section into the cylindrical body. Can be connected to each other to form a support bolt body, and it is possible to form a support leg by connecting each member to each other while easily and quickly stopping the rotation without taking time when connecting each member. You can do it.
