PROBLEM TO BE SOLVED: To provide a bearing capable of suppressing noise, vibration and looseness due to change of the direction and size of a load applied when a pivotally supported member is rotated.SOLUTION: On the inner peripheral surface of an outer ring 22, an outer ring side raceway groove 22a is formed, which has a contact part inclined so that its diameter becomes smaller as being away in a bearing center axial direction from a bearing center. On the outer peripheral surface of an inner ring 23, an inner ring side raceway groove 23a is formed, which has a contact part inclined so that its diameter becomes larger as being away in the bearing center axial direction from the bearing center. A holder 25 has elasticity, energizes a rolling body 24a from one side of the bearing center axial direction, and contacts the other side with the contact part of the outer ring side raceway groove 22a and the inner ring side raceway groove 23a. |
