It is rotatable. Further, hooks 5 having bay-shaped notches 5a are attached to the upper ends of the column pipes 3, 3, 3, and 3, respectively.

As shown in FIGS. 1, 2, and 3, each connecting tool 2 is a Y-shaped pipe joint having a plurality of pipe insertion holes 2x, 2y, 2z opened in three directions orthogonal to each other, and is a base pipe. The ends of 1, 1 are inserted into the pipe insertion holes 2x and 2y that open in the horizontal direction, respectively, and the lower end of the column pipe 3 is inserted into the pipe insertion hole 2z that opens vertically upward, and they are connected by connecting bolts 4, respectively. It is connected to the tool 2.

As shown in FIG. 3, since the outer diameter of the support pipe 3 is smaller than the inner diameter of the pipe insertion hole 2z, a gap G is formed between the outer peripheral surface 3g of the support pipe 3 and the inner peripheral surface 2n of the pipe insertion hole 2z. Has been done. The connecting bolt 4 is screwed into the female screw hole 2f formed in the short pipe portion 2w forming the pipe insertion hole 2z, and the tip portion 4a side of the connecting bolt 4 penetrates the through hole 3a opened in the column pipe 3. Then, it protrudes into the support pipe 3.

The inner diameter of the through hole 3a is larger than the outer diameter of the connecting bolt 4, and no female screw is formed on the inner peripheral surface of the through hole 3a. Since a gap G is formed between the pipe and the pipe, the strut pipe 3 can be tilted with the connector 2 as a fulcrum within the range of the gap.

In FIG. 1, the arrow line indicating tilt is shown in the left-right direction, but this is an example, and it is possible to tilt in all directions including front-back, left-right. The range of angles that can be tilted is not limited, but for example, 3 degrees to 3 degrees in all directions including front, back, left, and right based on the state in which the support pipe 3 stands vertically with respect to the base pipes 1 and 1 orthogonal to the horizontal direction. It can be tilted within a range of .5 degrees. The angle range in which the strut pipe 3 can be tilted can be changed by increasing or decreasing the gap G between the outer peripheral surface 3g of the strut pipe 3 and the inner peripheral surface 2n of the pipe insertion hole 2z.
