Abstract

See full text

In a valve operating system for an internal combustion engine, a support shaft supporting a roller is fitted in a fitting bore of a rocker arm, and a pin fixed in the rocker arm engages with an engage groove provided on the outer surface of the support shaft so as to extend in a direction tangential to an imaginary circle about the axis of the support shaft, an insertion bore which extends in a straight line and connects to an inner surface of a fitting bore at a position corresponding to the engage groove of the support shaft is provided in the rocker arm and the pin engaging with the engage groove by being inserted into the insertion bore is engaged with the rocker arm by crimping at least one end of the pin with flat punches so as to be fixed in the rocker arm. The pin can thus be fixed effectively in the rocker arm while maintaining the rigidity of the rocker arm.
