Abstract
The roller insertion groove of the inner ring of a crossed roller bearing is provided with an outer circumferential surface-side groove opening that is exposed to an inner rings-side V-groove. The groove opening is defined by circumferential direction opening edge that extends in the circumferential direction along the inner ring-side V-groove and side opening edges that extend from both ends of the circumferential direction opening to the ring-shaped end face of the inner ring. Concentration of stress occurs in the corners between the circumferential direction opening edges and the side opening edges. The circumferential direction opening edge is formed so as not to coincide with the minimum outer diameter section of the inner ring-side V-groove.
