Patent ID: 7926817

Claim:
A sealing apparatus comprising: a slinger that includes a cylindrical portion to be fixed to a peripheral surface of a first bearing ring, a first radially-extending portion extending from one axial end portion of the cylindrical portion toward a second bearing ring in a radial direction of the cylindrical portion, and a second radially-extending portion extending from the other axial end portion of the cylindrical portion toward the second bearing ring in the radial direction; a core metal member that includes a fixing portion to be fixed to the second bearing ring, and a distal end portion which is disposed between the first and second radially-extending portions in an axial direction of the cylindrical portion, and is spaced from the cylindrical portion in the radial direction; and an elastic member that includes a base portion fixed to the distal end portion to cover a surface of the distal end portion, and a lip portion brought into sliding contact with the slinger, wherein the lip portion includes a first axial lip which extends from an end portion of the base portion, disposed close to the cylindrical portion, toward the first radially-extending portion to contact the first radially-extending portion, and a second axial lip portion which extends from the base portion toward the second radially-extending portion to contact the second radially-extending portion, wherein surfaces of the first and second axial lips define a cylindrical portion-opposing surface which is opposed to the cylindrical portion in the radial direction in spaced relation to the cylindrical portion, wherein in a natural state of the elastic member, a radial distance between the cylindrical portion-opposing surface and the cylindrical portion is increasing generally uniformly from the first radially-extending portion toward the second radially-extending portion, wherein the base portion includes a distal end base portion fixed to the distal end portion of the core metal member and projecting from the distal end portion toward the cylindrical portion in the radial direction, wherein the first axial lip extends from the distal end base portion axially toward the first radially-extending portion and radially toward the cylindrical portion, and the second axial lip extends from the distal end base portion axially toward the second radially-extending portion and radially away from the cylindrical portion, and wherein the first and second axial lips extend from a point on the base portion of the elastic member radially between the cylindrical portion of the slinger and the distal end portion of the core metal member such that the core metal member is not interposed between the first axial lip and the second axial lip.
