In order to transport a large number of wheels 2, since the hub body 3 is formed with the male screw portion 7 for screwing the female screw portion 16 to fix the hub body 1 to the mounting portion 9. When packing in, by removing the hub body 1 from the mounting portion 9 of the wheel body 8, the wheel bodies 8 can be arranged side by side so that their centers coincide with each other in the width direction. Can be packed compactly. In addition, the hub axle 5 of the hub body 1 does not hit the wheel body 8 during transportation and the wheel body 8 is not damaged. In addition, the fitting hole 18
If a female screw portion is formed on the entire inner surface of the hub, the hub barrel 3 is loosened due to the looseness between the male and female screw portions. The front and rear sides of the 7-screw advancing direction are formed to have a size capable of fitting and supporting the hub barrel 3, so that the hub barrel 3 does not rattle. further,
The mounting portion 9 is provided on the rear end side of the hub barrel 3 in the direction in which the male screw portion 7 is threaded.
Since the flange 6 that abuts on the end surface of the fitting hole 18 on which the hub barrel 3 is fitted is provided, the hub shaft 5 axis and the wheel body 8 rotational axis center can be formed by abutting the flange 6 on the mounting portion 9 end surface. Can be made to coincide with each other, the hub 6 can be positioned in the screwing direction by the flange 6, and the screw portion due to overtightening of the male screw portion 7 can be prevented from being damaged. 7 screwing direction and wheel body 8
By matching the rotation directions of the above, rotational power transmission from the hub barrel 3 to the wheel body 8 can be increased.
