  The lower ring portion 30 includes an eye bolt 31, a nut 32, a base portion 33, and an L angle 34. The eyebolt 31 is an eyebolt having a long bolt portion, and the base of the head that is a ring is slightly bent. The nut 32 is a nut that engages with a bolt constituting the eyebolt 31. The base portion 33 is made of a member in which a strip-shaped iron plate is bent into a U shape so that the inner surfaces are equal to the diameter of the pipe body 10, and a hole through which the bolt portion of the eyebolt 31 passes is formed at the center. And is fixed by welding with the lower end of the pipe body 10 sandwiched so as to face obliquely. In addition, a long hole 12 is formed in the side surface of the pipe body 10 facing the hole of the base portion so that the eyebolt 31 passes through the pipe body 10 across the pipe body 10 from the hole of the base portion 33 and faces the long hole. An elongated notch 13 is formed at the lower end of the side surface. The bolt portion of the eyebolt 31 is exposed from the hole of the base portion 33 through the notch 13 and the elongated hole 12, and is fixed to the base portion 33 by engaging the nut 32 from the end portion. The hole of the base portion 33 is formed large so that the bolt portion of the eyebolt 31 can move with some play. The L angle 33 is a short general L angle, and the vertical portion is welded to the lower end side surface of the pipe body 10 on the side where the notch 13 is provided so that the horizontal portion protrudes from the lower end side surface of the pipe body 10. It is fixed. A notch 33a is formed in the center of the corner of the L angle 33 so that the eyebolt 31 passes. The horizontal portion of the L angle 33 is set to such a length that the pipe body 10 is almost vertical by abutting against the edge of the truck bed surface while the hook 21 of the upper hook portion 20 is hooked on the side of the track. .

Are adjusted so that the positions of the two are matched, and the bolt 23 is tightened to fix the moving portion 22. At this time, the protruding direction of the hook 21 and the protruding direction of the eyebolt 31 are made to coincide. The eyebolt 31 loosens the nut 32 so that the ring portion protrudes sufficiently downward. Thereafter, as shown in FIG. 3 (a), the hook 21 of the upper hook portion 20 is hung on the upper end of the lift G of the truck at the position where the loading platform hook F exists at the lower portion of the loading platform, and the state shown in FIG. 3 (b) is obtained. Here, since the hole of the base portion 33 of the lower ring portion 30 is formed to be large with play, the eyebolt 31 is tilted closer to the vertical. From this state, the nut 32 is tightened, and the eyebolt 31 is moved obliquely upward. At this time, it is desirable to attach a hand so that the ring portion of the eyebolt 31 is hooked on the loading platform hook F at the bottom of the loading platform. When the eyebolt 31 is sufficiently tightened, a state as shown in FIG. In this state, since the hook 21 of the upper hook portion 20 is pressed downward, it does not come off, and the tip of the horizontal portion of the L angle 33 is also pressed against the abutment side edge that abuts, so that the pipe body 10 is fixed without tilting. . Therefore, the track support holder X can be fixed to the track tilt G by the above operation. Next, as shown in FIG. 3 (d), if the support P is held from the upper end of the pipe body 10 and the bolts 11, 11 provided on the side of the pipe body 10 are tightened to fix the support P, Fixing the track to the tilt G is completed.
