A rocker arm is adapted for use with an engine including a push rod, a valve unit and a pivot ball disposed on a supporting frame. The rocker arm is connected pivotally to the supporting frame, and includes a main plate having a central opening defined by an upper edge, a horizontal lower edge disposed under the upper edge, and two curved lateral edges interconnecting the upper and lower edges. The lower edge has an intermediate portion formed with an outwardly flared recess that defines an upwardly facing socket engaging the pivot ball. A first arm plate is connected integrally to a lateral side of the main plate and is driven by the push rod. A second arm plate is connected integrally to an opposite lateral side of the main plate and operates the valve unit.
