In the figure, 1 is a cross rail mounting bracket, 2 is a circular column, and 3 is a cross rail. The horizontal rail mounting bracket 1 has a basic structure including a pipe member 4, a first auxiliary member 5, and a second auxiliary member 6.

As shown in FIGS. 2 to 4, the pipe member 4 is composed of two pieces 7 and 8 which are half-divided in the pipe axis direction, and one of the pieces 7 has a columnar shape at the center of the outer peripheral surface. A boss portion 9 is formed, and a through hole 10 is formed in the center portion thereof. Further, a through hole 12 is bored in a pipe portion 11 to which the horizontal rail 3 of the piece 7 is attached. A bolt 14 is fixedly provided on the pipe portion 13 to which the horizontal rail 3 of the other piece 8 is attached. The mating surface of the piece 7 and the piece 8 is such that the piece 7 has a convex outer peripheral side and a concave inner peripheral side, and the piece 8 has a concave outer peripheral side and a convex inner peripheral side. It is formed so that when the 7 and the piece 8 are combined, they are engaged with each other without being displaced in the radial direction.

As shown in FIG. 4, the first auxiliary member 5 is made of a short round bar material and has a through hole 15 at the center thereof, and the side to be attached to the circular column 2 is shown in FIG. As described above, the arcuate concave surface 16 is formed along the outer surface of the circular column 2.

As shown in FIG. 4, the second auxiliary member 6 is made of a short square bar, has a through hole 17 in the center, and the side to be attached to the circular column 2 is shown in FIG. As described above, the circular convex surface 18 is formed along the inner surface of the circular column 2.

Next, a method of using the cross rail mounting bracket 1 will be described with reference to FIGS. 1 to 4. First, the second auxiliary member 6 with the mounting bolt 19 attached to the through hole 17 is extended from the upper end of the circular column 2 to the through hole 20 (see FIG. 4) at the mounting position with the arcuate convex surface 18 along the inner surface. Then, the mounting bolt 19 is inserted into the through hole 17 and the through hole 20 at the mounting position so that the mounting bolt 19 projects outside the circular column 2. Next, the projecting portion of the mounting bolt 19 is inserted through the through hole 15 with the arcuate concave surface 16 of the first auxiliary member 5 first, and the arcuate concave surface 16 is added to the outer surface of the circular column 2. Next, after further penetrating the projecting portion of the mounting bolt 19 through the through hole 10 formed in the boss portion 9 of the pipe member 4, the nut 21 is attached to the mounting bolt 19 projecting from the through hole 10. tighten.
