摘要： With use of a fine copper-based powder, specifically a copper-based powder that contains particles each having a diameter of 45 μm or less by 80 weight % or more, an air permeability can be significantly reduced. When this copper-based powder is used, a sintered metal can be easily formed to contain copper by 40% or less (contain iron by 60% or more) to enhance abrasion resistance, and to have an oil permeability of 1.00 g/10 min or less to increase an oil film formation rate.

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.
