An apparatus for assisting in governing the idling rpm of an internal engine including a bypass line that bypasses a throttle valve in an air intake tube. A rotary slide valve secured to one end of a shaft which is controlled by a motor is rotatable in the bypass line to adjust air flow through the bypass line. The bypass line is integral with a lid-shaped housing part in which roller bearings juxtaposed the rotary slide valve is secured. The upper end of the shaft is rotatable in bearings carried by an upper housing part. The housing parts are secured together in axial alignment with each other.
