The inner race is fixed to the inner shaft by a clamping portion resulting from an and portion of the inner shaft. An annular stepped portion is formed on an outer end face of the inner race on a radially outward side thereof. A pulser ring is disposed within the stepped portion and is then held between the stepped portion and the clamping portion to thereby be fixed in place thereat.
