Abstract
A spacer is interposed between two adjacent balls and is formed into an elaborately designed cylinder-like configuration which is able to minimize noise and frictional loss due to mutual collision and impact of the balls. A lubrication let through hole is provided therein to further improve lubrication and cooling effects.
