a core; and a first elastic member, wherein the core includes:
a first tubular portion arranged such that an outer peripheral surface of the first tubular portion faces an inner peripheral surface of an outer ring of the bearing apparatus and extending along an axial direction of the bearing apparatus; anda first flange portion extending inward from the first tubular portion in a radial direction of the bearing apparatus, the first elastic member includes:
a thick portion arranged on the outer peripheral surface of the first tubular portion at one of opposite ends, in the axial direction, of the first tubular portion that is away from a bearing internal space, the thick portion being provided along a circumferential direction of the first tubular portion, anda thin portion extending on the outer peripheral surface of the first tubular portion from the thick portion toward the other end of the first tubular portion in the axial direction and provided along the circumferential direction of the first tubular portion, and an outer peripheral surface of the thick portion protrudes further outward than an outer peripheral surface of the thin portion in the radial direction, and a thickness of the thin portion in the radial direction is smaller than a thickness of the thick portion in the radial direction. |
