摘要： PROBLEM TO BE SOLVED: To improve an engine performance by incorporating a rocker arm, which is made by cold-forging raw materials made of metal wire rods, into the engine.
SOLUTION: Cold forging is performed to raw materials made of metal wire rods cut to a predetermined length so as to make a second intermediate raw material 34b which has a pair of side wall sections 2a and a base section 39 connecting each end portion in crosswise direction of the side walls 2a. Each first and second connection part is formed by punch working performed to the base section 39 of the second intermediate raw material 34b. When it is assumed that a roller 35 is deposed at a position corresponding to the position where the roller 35 should be deposed in a rocker arm inside the second intermediate raw material 34b where the punch working is to be performed, the roller 35 is made not to interfere with the base section 39.

摘要： PROBLEM TO BE SOLVED: To ensure strength of a first/second engaging part hitting a base end part of a valve unit and a tip end part of a rush adjuster simultaneously with attaining miniaturization and lightening of weight, by a structure integrally formed by applying press work to a sheet of metal plate. SOLUTION: Thickness of a connection part 15 for forming a first engaging part 17 is increased by concentrating thickness of a metal plate. A side wall part 14, 14 is not provided in both sides of this connection part 15 or provided only partly. Further, a difference between maximum and minimum values of stress generated at use time is set to within five times. In these methods, miniaturization and lightening of weight are attained while ensuring necessary strength.
