Beschreibung
Zusammenfassung:	A one-piece, cold-formed rocker arm is of the boat-type. It includes a one-piece metal body which is cold formed from a metal blank and is of generally U-shaped cross-sectional configuration throughout most of its length. The rocker arm body has two generally parallel side walls and a connecting bottom wall therebetween. The body also has inwardly-extending side walls extending from the parallel ones toward both ends of the body. The bottom wall extends between the side walls and has an opening for receiving a pivotal support, a recess for receiving a push rod at one end, and a pad for engaging an end of a valve stem at the other end. An elongate stiffening member extends between upper edges of side walls and specifically between the inwardly-extending side walls extending toward the push rod end of the body. The stiffening member preferably is a rod received in notches in the upper ends of the edges of the side walls and affixed thereto by resistance welding.
