Abstract
A rolling bearing cage includes: multiple rod members each of which is provided between adjacent two of multiple rolling elements that are arranged in a circumferential direction of a rolling bearing; and multiple coupling members each of which couples corresponding two of the rod members, which are adjacent to each other in the circumferential direction. Each of the coupling members is configured to be pivotable about an axis of a corresponding one of the rod members, which is connected to the coupling member, the axis extending in a longitudinal direction of the rod member, such that a relative angle between corresponding two of the coupling members, which are adjacent to each other in the circumferential direction, is adjustable.

A rolling bearing cage, comprising:
- multiple rod members each of which is provided between adjacent two of multiple rolling elements that are arranged in a circumferential direction of a rolling bearing;
- and
- multiple coupling members each of which couples corresponding two of the rod members, which are adjacent to each other in the circumferential direction,
- a movement restricting unit that restricts radial movement of the coupling members and that includes guided portions, the guided portions being formed in respective coupling members and contacting a bearing ring of the rolling hearing to restrict radial movement of the coupling members, wherein
- each of the coupling members is configured to pivot about an axis of a corresponding one of the rod members, which is connected to the coupling member, the axis extending in a longitudinal direction of the rod member, such that a relative angle between corresponding two of the coupling members, which are adjacent to each other in the circumferential direction, is adjusted.
A rolling bearing cage, comprising:
- multiple rod members each of which is provided between adjacent two of multiple rolling elements that are arranged in a circumferential direction of a rolling bearing;
- multiple coupling members each of which couples corresponding two of the rod members, which are adjacent to each other in the circumferential direction;
- and
- a movement restricting unit that restricts radial movement of the coupling members and that is formed by forming, in each of the coupling members, an elastic portion that is configured to be stretched in the circumferential direction of the rolling bearing through elastic deformation, wherein
- the rod members provided at respective end portions of each of the coupling members are pressed against an outer periphery of the corresponding rolling element by urging force of the elastic portion, which acts in such a direction that the elastic portion contracts, and
- each of the coupling members is configured to pivot about an axis of a corresponding one of the rod members, which is connected to the coupling member, the axis extending in a longitudinal direction of the rod member, such that a relative angle between corresponding two of the coupling members, which are adjacent to each other in the circumferential direction, is adjusted.
