2. The oil control member 32 removably blocks one of the oil guiding grooves 73, so that the present invention can adjust the oil passage of the lubricating oil injected through the oil filling hole 72 in accordance with different use angles, and average These circulation paths 6 are lubricated, thus having the effect of improving the lubricating effect.

3. By the oil storage tanks 74, the excess lubricating oil in the return passages 63 can be temporarily stored, and the lubricating oil can be controlled and the lubrication time can be prolonged.

4. The oil guiding member 40 and the corresponding inner cover body 33 are integrally formed, and the inner cover body 33 is detachably engaged with the outer cover body 31 by a hook, and the sealing cover The first latching portion 51 of the fifth latching portion 51 can be detachably engaged with the second latching portion 35 of the caps 3, thereby not only reducing the use of the bolts, but also increasing the mutual cooperation to avoid the combination error, thereby reducing the cost. The effect.

In summary, the present invention utilizes the lubrication system 4 to simultaneously lubricate the rolling elements (not shown) at both ends and the center, and then adjust the oil paths by the oil control members 32 and lubricate the circulation paths 6 on average.
