ROCKER ARM BODY USING PRESSING PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive rocker arm body using a pressed product capable of preventing a rocker arm from being released from a valve. SOLUTION: A rocker arm is guided at a top portion 10 of a valve stem 9 fitted to a grooved portion 2b opened downward, thereby preventing the rocker arm from being released from a valve. A top wall 15 of the grooved portion 2b is folded by press molding which using an axial line parallel to a strut of a roller in slide contact with a cam as a starting line. A fabricating cost can be reduced in comparison with the case where a separate part is used.
