PROBLEM TO BE SOLVED: To provide a bearing device that increases creep resistance without increasing a step during assembly.SOLUTION: A plurality of grooves 11 elongated from an axial end are formed on an inner peripheral surface 5b of an inner ring 5. The grooves 11 are elongated inward in an axial direction from both axial ends of the inner ring 5, and closed in a position of an axial intermediate part of the inner peripheral surface 5b of the inner ring 5. The plurality of grooves 11 are formed at regular intervals in a circumferential direction. |
