Abstract
A converting mechanism is provided between an EGR control valve driven by an actuator and an intake-air valve for generating negative pressure, so that the intake-air valve is also driven by the actuator. The converting mechanism has a cam plate rotated together with the EGR control valve and an arm rotated together with the intake-air valve. A cam groove formed in the cam plate is engaged with a driving pin of the arm. The intake-air valve is held at its maximum valve opening position, when the EGR control valve is rotated in a first angular range, while the intake-air valve is rotated from the valve opening position to a maximum valve closing position when the EGR control valve is rotated in a second angular range.
