PROBLEM TO BE SOLVED: To provide a turning bearing with a separator, in which a recess of the separator subject to fitting-in of a roller rolling surface is formed in a direction orthogonal to a direction parallel to a roller axis direction, and which makes assemblability proper by facilitating loading of the separator from a loading hole without adjustment of an attitude of the separator.SOLUTION: In a separator 4, an outer peripheral surface 33 facing outer and inner rings 1 and 2 is formed in such a manner that a shape of a vertical cross section in a movement direction is approximately quadrangular. In the separator 4 into which a roller rolling surface 11 of a roller 3 is fitted, arc-shaped concave parts 35 are symmetrically formed on both end surfaces 4 S in such a cross-like shape as to be orthogonal to each other, respectively, and a through-hole 37 configuring a lubricant reservoir part passing through the center between both the end surfaces 4 S is formed. In a cross-sectional shape in a bottom position of the concave part 35 of the separator 4, arc-shaped swelling parts 38 gradually swelling toward a peripheral edge of the through-hole 37 are formed in four directions. |
