PURPOSE:To easily discharge grease further prevent its leakage, by forming a slinger in a large external diameter while inserting felt between a fixed part and a rotary part so as to decrease a clearance between a bearing cover and the slinger. CONSTITUTION:Increasing the external diameter of a slinger 2 while decreasing a clearance between the slinger 2 and a bearing cover 1, felt 7 is inserted between the bearing cover 1 and the slinger 2. In this way, the discharging power of grease caused by centrifugal force increases while the slinger 2 approximates to about a discharge port 6, decreasing discharge resistance of the grease, thus facilitating its discharge. While the grease, whose reverse flow is prevented, can be prevented from its leakage from the discharge port 6. |
