。[Scope of Claim for Utility Model Registration] A rocker arm that swings following the movement of a cam in an internal combustion engine to open and close intake and exhaust valves, and is made of a steel plate punched into a predetermined shape and formed into two almost parallel straight lines. A main body having a cylindrical shape and having both ends bent at a substantially right angle along the longitudinal direction of the main body to form both side plate parts and a connecting part connecting them; bushings that are fitted and fixed in through holes formed in opposing positions of the parts; and bushings that are made of a material that is more wear resistant than the steel plate material, and that connect the cam directly or indirectly through other members. a cam copying member fixed to one end of the main body in order to imitate the above, and a female thread member fixed to the other end of the main body having a female thread hole into which a male thread member acting on the intake/exhaust valve is screwed. A steel plate rocker arm for an internal combustion engine, comprising:
