Abstract

PURPOSE: To supply a lubricating oil to a sliding surface properly in accordance with a shaft rotation by a method wherein an oil holding material is provided in a hollow shaft and an oil leading hole communicating to a cam surface is provided on a hollow shaft outside surface.
CONSTITUTION: In a hollow shaft 2 is tightly inserted a circular retaining pipe 3 which has an oil passing hole, and a cylindrical layer material 4 of a porous material is inserted into the pipe 3. A cam 5 is fitted tightly on an outside circumference 2a of the hollow shaft 2 and an oil leading hole 6 which communicates an inside circumference surface 2b of the hollow shast 2 to a sliding surface 5a of the cam 5 is provided. When the hollow shaft 2 is not rotating, a lubricating oil is kept in the layer material 4 and when the hollow shaft 2 is rotating, the lubricating oil reaches the sliding surface 5a of the cam 5 by a centrifugal force.
