Zusammenfassung:	PROBLEM TO BE SOLVED: To satisfy a requirement for reducing manufacturing cost in a swing arm fulcrum bearing which has been used hitherto. SOLUTION: In a fulcrum bearing unit 100, a plurality of rolling bodies 109 contact a member on the side of a shaft 101 as an internal member at one point on a conical orbit face 153, for example. Furthermore, the plurality of rolling bodies contact a sleeve 102 as an external member at two points on a conical orbit face 151 and a conical orbit face 152, for example. Then, processing for improving surface roughness Ra (reducing surface roughness Ra) is applied only to a surface-roughness improving processing region which is part of the conical orbit face 153.
