Abstract

PURPOSE: To not only heighten the strength of a shaft and but also carry out stable lubrication, by making the inner part of the shaft of a high-density sintered material and making its outer part of a porous low-density sintered layer which contains oil.
CONSTITUTION: The inner part 16 of an oil-containing sintered shaft 12 is made of a high-density or bulky material. An outer low-density sintered layer 17 with a high void ratio of about 20% is provided on the peripheral surface of the inner part 16. The outer sintered layer 17 is caused to contain oil for lubrication.
