Abstract: A method for casting a rocker arm made of light alloy for use in an overhead cam shaft type valve operating mechanism of an internal combustion engine, which rocker arm includes a thick-walled bearing section to be fitted on a rocker arm shaft and is integrally provided with a wear-resistive piece having a protrusion on its rear surface and adapted to abut a cam. After molten metal has been injected under pressure into a metallic mold for the rocker arm, a secondary pressurizing force directed in the direction of an imaginary center axis of a rocker arm shaft is exerted by means of a pressurizing rod. In the metallic mold for the rocker arm, a sprue is provided close to the position where the wear-resistive piece is disposed with respect to the position where the bearing section is formed, and the direction of the sprue is directed towards the position where the wear-resistive place is disposed.

Abstract: A one-piece, cold-formed rocker arm of the cam-follower type is provided. The rocker arm includes a one-piece metal body cold formed from a metal blank and being of inverted U-shaped cross section throughout most of its length. The body has a top wall with depending, structurally-integral side walls. An intermediate, convex portion of the top wall has an opening extending therethrough with an axle extending between the side walls below the opening. A cam-contacting roller is rotatably mounted on the axle and has a circumferential surface exposed at the opening to engage a cam. The rocker arm body has a recess at one end portion to receive a lifter post and an additional recess at another end portion to receive an end of a valve stem. The one end portion of the body is wider than the remainder of the body. Ribs are formed at the lower edges of the body and extend along the intermediate portion of the body between the two end portions. The outer edges of the ribs do not extend beyond the side walls of the body at the one end portion thereof.
