1. An anti leakage device of lubrication oil for a fan, comprising:
a hub seat;
a sleeve, being provided on the hub seat and having a bearing therein to form an oil storage part for receiving lubrication oil; and
a hub, being provided on the hub seat and having an annular recess at the inside thereof for being inserted with the sleeve;
whereby, leakage of the oil storage part can be avoided due to provision of the annular recess.
2. The anti leakage device of lubrication oil for a fan as defined in claim 1, wherein the hub is provided with a rotational shaft, which is inserted into the sleeve, so that the hub can be pivotally attached to the hub seat.
3. The anti leakage device of lubrication oil for a fan as defined in claim 2, wherein a durable pad is disposed in the sleeve to contact with an end of the rotational shaft to reduce frictional resistance during the shaft rotating.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
