て構成する。 The mounting body B has a mounting hole 6 into which the guide bushing A can be fitted, but the wedge portions 3a,
Both tapered surfaces 7 inclined in the vertical direction are provided on both internal side surfaces of one end of the mounting hole 6 into which the mounting hole 3b is inserted.
a, 7b, and a screw hole 9 is provided at the bottom of one end of the mounting hole 6 between both tapered surfaces 7a, 7b.
A spring washer 12 is formed on the head 8a side.
The tightening bolt 8 to be fitted is inserted into both recesses 11a and 11b.
It is configured so that it can be screwed into the screw hole 9 by passing it through between the holes.

ａが強く締付けられることになる。 When installing the pedestal 1 on the mounting body B side, fit the head 1a of the pedestal 1 into the hole 2 of the guide bush A, and then insert the guide bush A into the mounting hole 6 of the mount B. Once fitted, tighten the tightening bolt 8 with spring washer 12 on both wedge parts 3a and 3b.
Insert it inward between the recesses 11a and 11b, and screw the tip into the screw hole 9. From the state where the head 8a side is joined to the end surfaces of both wedge parts 3a and 3b, rotate the tightening bolt 8 to tighten the screw. As the screw is screwed into the hole 9, the guide bush A is pushed by the head 8a, and the tapered surfaces 4a and 4b align with the tapered surface 7.
a, 7b, and the wedge parts 3a, 3b gradually approach each other due to the wedge action.As a result, the guide bush A enters into the mounting hole 6, and the hole 2 is narrowed, and the leg Head 1 of Pillar 1
a will be strongly tightened.
また、脚柱１の頭部１ａはテーパー付きのた

特長を有する。 In this way, the present invention has a guide bushing having a tapered hole formed on one side into which the tapered head of the tip of the pillar can be inserted, and two corresponding wedges formed on the other side from the divided parts around the hole. A tapered surface is formed on the outer surface of both wedge parts, and a mounting hole into which the guide bush can be inserted is formed in the mounting body fixed to the side of the seat body, top plate, etc. Tapered surfaces are formed on both inner sides of the mounting hole in the part corresponding to both tapered surfaces of the part, and the guide bushing is installed by threading the tightening bolt that fits between both wedge parts into the threaded hole at the bottom of the mounting hole. Because it is configured so that it can be press-fitted into the mounting hole, the pillar can be easily inserted and removed from the guide bushing, and the wedge part of the guide bushing can be easily attached and removed by the simple operation of tightening the bolts. Due to the wedge action, the head of the pedestal can be strongly tightened through the hole of the guide bush, resulting in a vertical mounting structure, and has the advantage that it can be easily implemented with a simple structure.
