CLUTCH RELEASE BEARING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a clutch release bearing device capable of reducing torque loss by suppressing elastic pressing-on force of a contact lip for an inner ring, and improving muddy-water resistance characteristics.

SOLUTION: An extending cylinder 36 extending in the axial direction is formed in one end of the inner ring 35 of a clutch release bearing 30. A flange 37 is provided at an extending end of the extending cylinder 36 so as to project radially outward. A sealing member 90 is mounted between the extending cylinder 36 of the inner ring 35 and an outer ring 31 of the clutch release bearing 30. An outer diameter side fixation section 93 fixed to the outer ring 31 is formed in the outer diameter end of the sealing member 90. A first lip 95 is formed in the inner diameter end of the sealing member 90 to exert sealing action to the periphery of the extending cylinder 36 of the inner ring 35. A second lip 96 is formed in the sealing member 90 to exert sealing action in cooperation with the flange 37 of the inner ring 35.
