BALL BEARING

WIPO Patent Application WO/2023/135669

A1

In a cross section of a ball bearing 10 that includes a central axis C2, a minor angle θ1 formed by an inclined surface 23 and the central axis C2 is smaller than a minor angle θ2 formed by an inclined surface 24 and the central axis C2. In a cross section that includes a central axis C1, the intersection point between a straight line L1 passing through a radially-first-side large circle BC1 and a radially-second-side large circle BC2 and a radially-second-side surface of a second imaginary torus T2 is designated as an end point a, the intersection point between the straight line L1 and a radially-first-side surface of a first imaginary torus T1 is designated as an end point b, the farthest axially second side of a second outer ring raceway 22 on the radially second side is designated as an end point c, the farthest axially second side of the inclined surface 23 on the radially first side is designated as an end point d, a point located on the inclined surface 23 on the radially first side and being nearest to the end point c is designated as an end point e, the radially-second-side large circle BC2 is designated as a sixth end point f, and either the length of segment ab is greater than the length of segment cd, or the length of segment ab is less than the length of segment cd, the length of segment ab is less than the length of segment ce, and the length of segment fb is less than the length of segment fe.
