SCM, SC, SPH, and SPC are used, and the stainless steel 19 is, for example, SUS304. The steel plate 18 on the inner side is charcoal hardened and set to have a hardness of HR A 73 or higher. However, if the steel plate 18 is of high carbon content, it may be quenched without being decarburized. An annular notch 20 is cut into the upper end of the stainless steel 19 so that the steel plate 18 is exposed to the outside and the plating adheres well.
The 0 part is colored with manganese phosphate, zinc phosphate, parka, coating, etc. for rust prevention treatment, and is also buffed to form a ring-shaped pattern on the upper part of the ball holder 9. This improves the appearance.

実用的効果は著大である。(Effect of the invention) The wheel body of the bicycle bearing of the invention is composed of a clad steel plate having a steel plate 18 on the inner side and a stainless steel plate 19 on the outer side.
8 is hardened, so even if the inner steel plate 18 in contact with the sphere is hardened over the entire area, the stainless steel 19 on the outer surface can be effectively reinforced to prevent cracking. Breaking strength can be dramatically improved. In addition, since the steel plate 18 can be made hard over the entire area, the steel plate 18 can be made as thin as possible,
Materials can be saved and manufacturing costs can also be reduced. Moreover, since the outer surface is made of stainless steel 19, there is no need for special anti-corrosion treatment, the trouble of plating or painting the entire outer surface is eliminated, and manufacturing is extremely simple, resulting in great practical effects.
