Document Type and Number:
Japanese Patent JP5182068
Kind Code:
B2
Abstract:
Both an end surface (105) of a first rib (71), over which a first cylindrical rollers (8) slide, and an end surface (104) of a second rib (44), over which the first cylindrical rollers (8) slide, slope to approach the perpendicular bisector plane of a first cylindrical raceway surface (72) of an outer ring (6) or slope to be spaced away from the perpendicular bisector plane as it goes outward in a radial direction in a cross section of the outer ring (6) taken in an axial direction. A first sliding contact portion (110) of each first cylindrical roller (8), which is in sliding contact with the end surface (105) of the first rib (71), and a second sliding contact portion (111) of each first cylindrical roller (8), which is in sliding contact with the end surface (104) of the second rib (44), both are located inward in the radial direction with respect to an orbital cylindrical plane of the first cylindrical rollers (8).
