In the device, a first lip forms a non-contact seal between the release fork side end of the outer ring and the outer circumferential edge of the alligator part of the inner ring, and an outer circumferential surface of the cylindrical part of the inner ring on the inner side of the bearing from the first lip. a second forming a contact seal between
What is claimed is: 1. A sealing device for a release bearing, comprising: a seal body having a lip, the second lip having a shape that protrudes radially inward in a bent shape. (2) In the release bearing sealing device according to claim 1, the tip of the second lip is
A sealing device for a release bearing, characterized in that the contact angle is set to allow the bearing to open inward. (3) In a release bearing sealing device for outer ring rotation, in which the radially inward alligator portion of the outer ring is placed on the clutch spring side, and the radially outward alligator portion of the inner ring is placed on the release fork side, the outer ring is located on the release fork side. The end portion is provided with the seal body according to claim 2, and the clutch spring side end portion of the inner ring is provided with a seal member that forms a non-contact sealing portion between the inner ring and the inner surface of the alligator portion of the outer ring. 1
A seal body is provided, which includes a lip and a second lip that forms a contact seal between the inner surface of the alligator portion of the outer ring on the outer side of the bearing than the first lip, and the second lip is arranged on the outer side of the bearing. A sealing device for a release bearing characterized by being set at a contact angle that allows it to open in the opposite direction.
