Zusammenfassung:A rocker arm for an internal combustion engine is disclosed. The rocker arm has a cold-formed, one-piece metal body with a narrow width and a substantial depth. The body has a pad at one end for engaging an end of a valve stem and has a socket at the other end for engaging the upper end of a push rod. An intermediate portion of the body has a large opening of generally trapezoidal configuration with a lower edge longer than an upper edge. A middle portion of the lower edge has a structurally-integral, outwardly-flared portion defining an upwardly-facing socket for engaging a pivot ball about which the rocker arm can pivot during operation.
