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.

Ball bearing

An oil deterioration suppressing apparatus is provided. The apparatus may include a filtering portion including a filter element for filtering oil, and a deterioration suppressing portion including a powdery deterioration retarder which suppresses deterioration of oil. The deterioration suppressing portion may include a flow passage wall which holds the powdery deterioration retarder and defines an oil flow passage, and the powdery deterioration retarder includes mesoporous inorganic material.

Oil deterioration suppressing apparatus

When temperature of lubricating oil is raised at a time of low-temperature, of an outer peripheral side of a radial plain bearing in a bearing retaining unit, heat is not supplied from a heating medium in a thermal medium flow path on the outer peripheral side of a halved bearing metal in a bearing retaining unit body, which has a large thermal capacity, and instead, heat is supplied from the heating medium in the thermal medium flow path on the outer peripheral side of a halved bearing metal in the cap, which has a small thermal capacity.
