Document Type and Number:
WIPO Patent Application WO/2024/018524
Kind Code:
A1
Abstract:
A roller bearing 1 according to the present disclosure is equipped with an inner ring 2, an outer ring 3, a plurality of rollers 4, and a resin cage 6 which holds the plurality of rollers 4 so as to be separated from one another by an interval in the circumferential direction. The cage 6 has a pair of ring-shaped bodies 10 and a plurality of columns 12 which connect the pair of ring-shaped bodies 10. Each of the plurality of columns 12 has a column main body 14 and a hook part 16, which is provided to the column main body 14 and prevents the rollers 4 inside a pocket 7 from falling out in the radial direction. The column main body 14 has a pair of projecting parts 20 which extend from the pair of ring-shaped bodies 10 in the axial direction, and a connecting column 22 which connects the pair of projecting parts 20. The connecting column 22 has an outside surface 24 which is oriented toward the outside 6a in the radial direction. The position of the outside surface 24 in the radial direction is farther toward the inside 6b in the radial direction relative to the positions in the radial direction of a pair of radial-direction surfaces 20a of the pair of projecting parts 20. The hook parts 16 are provided so as to project toward the outside 6a in the radial direction from the outside surface 24.
