摘要： When a bearing member (bearing sleeve (8)) is formed of a sintered metal comprising a middle relief portion (E), a lubricating oil can be impregnated and retained in inner pores of the sintered metal. Thus, when the lubricating oil in a middle relief space (E0) is drawn into a radial bearing gap side and lubricating oil pressure in the middle relief space (E0) decreases, the lubricating oil impregnated in the inner pores of the bearing sleeve (8) is drawn out from surface pores of the middle relief portion (E) and supplied into the middle relief space (E0). Thus, generation of negative pressure is prevented.
