<p>In the disclosed sintered oil-containing bearing, grooves (3) with triangular cross-sections are formed in rings around axial ends (2b) of bearing members (2) that are formed from a sintered metal and contain a lubricating oil in internal holes. A grease (10) is placed in said grooves (3) on the groove-base-side of entrance openings. The surface roughness of the grooves (3) is less than the surface roughness of bearing surfaces (2a) on the bearing members (2).</p> |
