Zusammenfassung:	PROBLEM TO BE SOLVED: To actualize a structure with a high load capacity for hardly causing rolling elements to ride on both large-diameter and small-diameter side outer ring engaging margin parts in the state of being incorporated in a rotary machine device and preventing the slip-off of an outer ring in the axial direction, without increasing an assembling cost.SOLUTION: A curvature radius Rof the contact angle side half part and a curvature radius Rof the opposite side half part of a large-diameter side outer ring raceway 6a satisfy 1.1R
