Patent ID: 6974259

Claim:
A vehicle-use bearing device comprising: a hub wheel having a hollow shaft portion; a rolling bearing fitted around the hollow shaft portion of the hub wheel; and a constant velocity joint tiltably coupling an input shaft with the hub wheel; wherein the constant velocity joint has an outer ring which comprises an outer ring cylindrical portion, said cylindrical portion housing an element for tilting guide with respect to the input shaft and an outer ring shaft portion, said shaft portion being provided adjacently to the outer ring cylindrical portion; wherein a shaft end on a vehicle inner side of the hollow shaft portion of the hub wheel is caulked on an outer end face on a vehicle inner side of an inner ring of the roiling bearing; wherein the outer ring shaft portion of the constant velocity joint is inserted into the hollow shaft portion of the hub wheel so as not to be circumferentially rotated; said hub wheel having an outer side opening and an intermediate portion, said intermediate portion being intermediate said vehicle inner side shaft end and said outer side opening of said hub wheel; said constant velocity joint having a vehicle inner side, a vehicle outer side shaft end and an axially intermediate portion, said axially intermediate portion of said constant velocity joint being intermediate said vehicle inner side and said vehicle outer side shaft end of said constant velocity joint; and wherein a held portion provided between said axially intermediate position and said vehicle outer side in the hollow shaft portion of the hub wheel is axially sandwiched between an axially intermediate position and said vehicle outer side in the outer ring shaft portion of the constant velocity joint, whereby the outer ring of the constant velocity joint is connected to the hub wheel in the manner in which the outer ring cylindrical portion of the constant velocity joint is free of contact with the shaft end on the vehicle inner side of the hollow shaft portion of the hub wheel caulked on the outer end face on the vehicle inner side of the inner ring of the rolling bearing.
