Abstract
A rolling bearing includes an outer ring, an inner ring, a rolling element disposed in a rollable manner between the outer ring and the inner ring, and an O-ring made of an elastic body and fitted to a peripheral groove provided at an outer peripheral surface of the outer ring. A first bottom surface is provided at a center of the peripheral groove in an axial direction, and a second bottom surface is provided at an end part of the first bottom surface in the axial direction. The second bottom surface extends in a circumferential direction and has a smaller diameter than the first bottom surface.

A rolling bearing comprising:
- an outer ring;
- an inner ring;
- a rolling element disposed in a rollable manner between the outer ring and the inner ring;
- and
- an O-ring made of an elastic body and fitted to a peripheral groove provided at an outer peripheral surface of the outer ring, wherein
- a first bottom surface is provided at a center of the peripheral groove in an axial direction,
- a second bottom surface is provided at an end part of the first bottom surface in the axial direction, the second bottom surface extending in a circumferential direction and having a smaller diameter than the first bottom surface, and
- the first bottom surface has a shape substantially parallel to the axial direction.
