ABSTRACT:
A VA apparatus includes a rocker arm coaxially swingably supported on a support shaft. The rocker arm is swung by torque transmitted from an engine to operate an engine valve and includes a first arm to which torque is transmitted and a second arm for operating the engine valve. The first and second arms, which are separate and distinct from each other, are swingable relative to each other. Bolts are provided to fix the first and second arms in a predetermined relative angle position.
