Beschreibung
Zusammenfassung:	A holder has a protrusion which protrudes from a side surface at a side opposite in an axial direction with respect to a rolling element held in a pocket toward the side opposite in the axial direction. An oil supply hole which penetrates through the holder from the side surface to a surface at a side of the rolling element in the axial direction is formed in the holder. When the holder rotates, the protrusion guides oil into the oil supply hole, and the oil is introduced from the side surface of the holder to the surface on the side of the rolling element.
