An annular seal, tapered rollers and a retainer are arranged on the outer peripheral surface on the flange section side of an inner shaft to form an inner shaft assembly. An annular spacer capable of being split in the circumferential direction is arranged between the flange section of the inner shaft and the annular seal. With the annular spacer supporting the annular seal, an outer ring is pushed into the inner shaft assembly to assemble the annular seal to the outer ring, and then the annular spacer is split and taken out.
