Abstract: Raw material powder containing metal powder as a main component is molded to form a metal powder molded body (3′), and the metal powder molded body (3′) is sintered to form a metal substrate (3). Further, a lubricating member (4) is made of an aggregate of graphite particles (13), and at least a part of a bearing surface (11) is formed of the fabricating member (4). The lubricating member (4) is fitted into the metal powder molded body (3′). After that, the metal powder molded body (3′) is sintered, and at this time, the lubricating member (4) is fixed onto the metal substrate (3) with a contraction force (F) generated in the metal powder molded body (3′).

Abstract: A separator 8 including a solid lubricant is disposed between adjacent rolling elements 7. Relative movement of the adjacent rolling elements 7 and the separator 8 in a direction of separating apart in a circumferential direction is restricted by restricting members 10, and the restricting members 10 are disposed at plural locations in the circumferential direction. A minute gap α is provided between the adjacent restricting members 10, to allow relative movement therebetween. This can provide a solid-lubrication rolling bearing capable of stably preventing rotational locking and unintended disassembling of the bearing for a long period.
