PROBLEM TO BE SOLVED: To prevent an edge load to be applied on a second inner-ring raceway 9 by making crowning conducted to the second inner-ring raceway 9 appropriate notwithstanding an elastic deformation of a second inner ring 13 that occurs associated with the formation of a caulking section 16. SOLUTION: The drop amount of the crowning conducted to the second inner-ring raceway 9 is made small at the external edge and large at the internal edge. The problem is solved thereby, since the drop amount at the internal edge is made appropriate in conjunction with the elastic deformation. |
