As the steel plate material, a carburized steel plate can be used, and as the heat treatment, carburized quenching can be used. Examples of the carburized steel include nickel chrome steel (SNC), nickel chrome molybdenum steel (SNCM), chrome steel (SCr), and chromium molybdenum steel (SCM). Among these, nickel chrome steel (SNC) and nickel chrome molybdenum steel (SNC)
M) is a material that is less likely to cause excessive carburization and has excellent mechanical properties, but is difficult in terms of cost because it contains expensive nickel Ni as an alloying element. Considering the mechanical properties required for the inner ring, SNC steel, SNCM
With steel, there is a sense of excessive quality, and cost cannot be balanced. In contrast, chrome molybdenum steel (SCM)
Is hard to cause excessive carburization, has good hardenability, and is relatively inexpensive as compared with SNC steel and SNCM steel. Further, the mechanical characteristics required for the inner ring of the clutch release bearing device can be sufficiently satisfied. For this reason, chrome molybdenum steel (SC) is used as the material of the inner ring 3a.

A seal press-fitting portion 3b4 into which the outer diameter side portion of the second seal member 3f is press-fitted is provided. Seal press-fit part 3 at one end
A counterbore 3b5 is formed between b3 and the raceway surface 3b2 by removing the shoulder of the raceway surface 3b2, and a slight step δ2 is provided between the inner diameter surface of the counterbore 3b5 and the bottom of the raceway surface 3b2.

b, ball 3c, retainer 3d, and seal member 3e,
This can be performed at low cost by press-fitting (squeezing) the inner race 3a from the other end side into the inner diameter portion of the assembly incorporating the 3f or the like. In this case, in order to further reduce the cost, it is desirable that the inner ring 3a be stuck at normal temperature, not under heating. In consideration of the assemblability at room temperature, it is desirable that the step δ1 of the inner ring 3a is as small as possible. On the other hand, if the step δ1 is too small, the inner ring 3a may come off. Accordingly, the step δ1 is a value that satisfies both conditions, that is, a value that allows the inner ring 3a to be easily squeezed at room temperature and that does not damage the surface of the ball 2c during the squeezing and that the inner ring 3a can be reliably prevented from coming off. For example, 30 μm (in the drawing, the step δ1 is exaggerated)
It is desirable to set to about. The step δ2 on the outer ring 3b side may be substantially the same as the step δ1 on the inner ring 3a side, but is generally larger than the step δ1.

きる。The dimensions of the step δ1, the coaxiality of the counterbore 3a5, and the like can be accurately obtained by simultaneously grinding the counterbore 3a5 and the raceway surface as described above. Accordingly, it is possible to improve the assembly workability in the inserting process. Further, the seal surfaces 3a3 and 3a4 are simultaneously ground with the inner raceway surface 3a2, or the seal press-fit portion 3b3 of the outer race 3b is formed.
And 3b4 are simultaneously ground with the outer raceway surface 3b2,
