Abstract

PURPOSE: To enhance wear resistance, by conjoining ceramic to the sliding surfaces of the rocker arm and cam of an automobile engine.
CONSTITUTION: A groove 7 is provided on the sliding surface of the body 1 of a rocker arm, which slides on a cam shaft. A ceramic pad 2, which includes a protruded part 3 which is fitted in the groove 7, is bonded on the rocker arm body 1 by an adhesive 4. After that, the sliding surface 6 of the pad 2 is finished to a roughness by a diamond-grain whetstone of #300 in grain size on the basis of a prefinished shaft A and a prefinished surface B for the rocker arm body 1.
