PROBLEM TO BE SOLVED: To suppress occurrence of poor lubrication of a self-lubrication type bearing device by suppressing positional deviation of holes as a lubricant passing route.SOLUTION: A self-lubrication type bearing device includes a rotary main shaft 3, a thrust collar 4 disposed integrally with the rotary main shaft 3 and projecting to a radial outer side of the rotary main shaft 3, a circulator 9 disposed in a state of surrounding the thrust collar 4 from an outer peripheral side, and provided with a projection 10 on its outer peripheral face, and a stopper portion 22 for restricting the rotation in the circumferential direction of the circulator 9 by being brought into contact with the projection 10 of the circulator 9 from the circumferential direction, and a face 24 kept into contact with the projection 10 of the stopper portion 22 is elastically movable in the circumferential direction. |
