Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fulcrum bearing unit stabilizing torque of a swing arm by reducing fluctuation of a rolling element load and facilitating its control. SOLUTION: Either raceway surface of an inner side raceway surface or an outer side raceway surface contacted by a ball 109 is used as two mutually crossing contact surfaces (conical raceway surfaces 120, 121) having conical face shapes. By this, in the fulcrum bearing unit, the ball 109 is contacted at three points by the contact faces having the conical face shapes. COPYRIGHT: (C)2010,JPO&INPIT
