For this reason, the rear fork that suspends the rear wheel is made of light alloy to reduce weight. Furthermore, the axle shaft that rotatably supports the rear wheel is made into a hollow axle shaft A to reduce weight, as shown in FIG. The axle shaft A has one hollow end expanded,
A bolt-shaped head B is provided, which is passed through the shaft hole E of the axle fitting D of the rear fork C and is fastened.

それでも鋼板が反ったりする不都合がある。Problems to be Solved by the Invention Since the hollow axle shaft A has one end expanded by a header to form the head B, there is a limit to how large it can be made, and it cannot be made to any size. On the other hand, the rear fork C and the axle fitting D at the rear end of the rear fork C are made of light alloy to reduce weight, and when the axle shaft A is passed through the shaft hole E of the axle fitting D and tightened, the area that the head touches is reduced. However, there is a problem in that the surface pressure becomes high and the axle fitting D, which is made of a soft material, causes buckling. Also, axle metal fitting D
A steel plate splint is added to prevent buckling, but
However, there is still the disadvantage that the steel plate may warp.

ことを目的とする。[0004] In view of these points, the present invention allows the head piece provided at the end of the axle shaft to be made to any size, thereby reducing the surface pressure applied to the axle fitting when it is fastened, thereby preventing buckling. The purpose is to obtain an axle shaft for the rear wheel of a motorcycle.

Insert the piece, place the head piece on the outer tsuba, push the punch into the hollow shaft on the outer tsuba side, and expand it.
The head piece is fixed to the outer flange end of the hollow shaft.

As a result, when the axle shaft is passed through the shaft hole of the axle metal fitting at the rear end of the rear fork and tightened, it is possible to create a large tightening surface between the head piece and the axle metal fitting, which greatly reduces the surface pressure on the fastening surface. This can prevent buckling of the axle fittings.

An outer flange 3 is provided at one end. On the other hand, a rectangular head piece 5 having a serration hole 4 in the center is provided, the serration hole 4 of the head piece 5 is inserted into the hollow shaft 2, and the head piece 5 is brought into contact with the outer flange 3. Then, as shown in FIG. 3, the punch 6 is press-fitted into the hollow 1 on the outer flange 3 side, the hollow shaft 2 is expanded, and the head piece 5 is inserted into the serration hole 4. is fixed to the end of the outer flange 3 of the axle shaft 7. Incidentally, a screw 9 for tightening a nut 8 is carved on the opposite side of the head piece 5 of the axle shaft 7.
