Each of the two split outer ring halves includes an oil hole penetrating the split outer ring half in a radial direction thereof and an oil groove formed on an outer diameter surface of the split outer ring half along a circumferential direction thereof to allow the oiling passage and the oil holes to communicate with each other. Each of the oil holes is disposed at a position located at an angle of within 45° from the joint surface of the split outer ring halves in an opposite direction to a rotating direction of the shaft.
