    摘要： A roller bearing retainer (13) includes a pair of annular ring parts (14) and a plurality of column parts (15) each including a column center part (16) provided in an axial center region so as to be positioned relatively on the radial inner side, a pair of column end parts (17) provided in axial end regions so as to be positioned relatively on the radial outer side, and a pair of column sloped parts (18) positioned between the column center part (16) and the pair of column end parts (17), and connecting the pair of ring parts to each other. A thickness of each part of the column center part, the pair of column end parts, and the pair of column sloped parts is smaller than a thickness of a boundary part between the adjacent parts.

    摘要： A roller bearing retainer 33 includes a plurality of column parts 15 each containing a column center part 16, a pair of column end parts 17, and a pair of column sloped parts 18 positioned between the column center part 16 and each of the pair of column end parts 17, and a pair of annular ring parts 14 connected to longitudinal one side and the other side ends of the plurality of column parts 15, and having a flange part 19 extending from a position connected to the column part 15 toward the radial inner side. Thus, the column center part 16, the pair of column end parts 17, and the pair of column sloped parts 18 are formed by expanding both axial ends of a cylindrical member, and the flange part 19 is formed by compressing the cylindrical member in an axial direction, and at the same time a thickness of a boundary part between adjacent two parts of the column center part 16, the pair of column end parts 17, the pair of column sloped parts 18, the flange part 19, and the pair of ring parts 14 is made larger than a thickness of each part of the column center part 16, the pair of column end parts 17, the pair of column sloped parts 18, the flange part 19, and the pair of ring parts 14.

    摘要： A positioning protrusion 14 is provided in a center of an outer diameter surface of a halved outer ring 11a in both circumferential and axial directions. The positioning protrusion 14 is configured to engage with a housing, which is placed on an outer diameter side of the halved outer ring, to position the halved outer ring 11a with respect to the housing. A protruding portion 17a and a recessed portion 17b are provided in each abutting portions 16a, 16b where a pair of the halved outer rings 11a abut on each other when fitted on a rotary shaft that is supported by a roller bearing. The protruding portion 17a and the recessed portion 17b are configured to mesh with each other to restrict axial movement of both halved outer rings 11a. The protruding portion 17a and the recessed portion 17b are point-symmetric with respect to a center 20 of the positioning protrusion 14.
