The guide member including: an annular guide surface arranged at a position different form the second raceway surface in an axial direction; a plurality of flow paths which are separately provided in the axial direction and in which compressed air for supplying lubricating oil flows; and discharge openings which spray the compressed air to a guided surface. An annular cage that holds the plurality of rolling elements at given intervals in a circumferential direction and has the guided surface which opposes the guide surface such that the guided surface can slidably contact the guide surface.
