A female thread 17 is formed inside thereof for screwing an adjuster star member 11, which will be described later. Next, the adjuster star member 11 is longer than the guide tube 10 described above, has a length such that it can penetrate through the guide tube 10 and protrude outward from both ends of the guide tube 10, and is screwed into the female thread 17 inside the guide tube 10. The cylindrical body 19 has a male thread 18 on its outer diameter and outer surface, and has through holes 20 formed in the upper and lower sides of the cylindrical body 19. Through the support step 21 inside this through hole 20, the through hole 20 is located below the wide hole on the entrance side, that is, below the support step 21.
It is composed of a cylindrical body 19 formed with a slightly narrower support step 21, and preferably has a flange portion 22 at the lower end of the cylindrical body 19 as shown in the figure, or a hemline at the bottom of the cylindrical body 19. An example is adopted in which the supporting surface is formed in a wide, spread-like manner. Bolts and nuts 12 for fixing these members pass through the through hole 20 below the support step 21 of the adjuster star member 11 as shown in the example, and are attached to the mounting portion of the wheel device 3, that is, as shown in the example. In this case, a bolt and a fixing nut having a thickness and length that can be inserted through the plate of the connecting member 6 are prepared.

Therefore, when attaching the wheel device 3 to the storage body 1 using such a member, the cylinder body 16 of the guide tube 10 is inserted into the mounting hole 13 of the storage body bottom plate 8, and the screws 15 etc. are driven into the flange portion 14. Sole plate 8
The main guide cylinder 10 is fixed, and in this state, the adjuster star member 11 is screwed in from below to adjust the positions of the bottom plate 8 and the tip of the adjuster star member 11, that is, the wheel device 3 located on the lower end surface of the adjuster star member 11 is adjusted. After adjusting the position with the top surface of the bolt 12
The nut 12 inserted and positioned on the bottom surface of the connecting member 6
and connect the adjuster star member 11 to the wheel connecting member 6.
It is fixed on top. As the rotating device 23 for the adjuster star member 11, a device as shown in FIG. 5 is used. This rotating device 23 is configured such that a rod 25 can be inserted into one end of a shaft body 24, and a rotating piece 26 is inserted into the other end from one end of a cut groove 27 to insert the rod 25.
