ABSTRACT:
An idling control apparatus for an internal combustion engine includes a valve element amounted in a passage for air for idle running of the engine bypassing a throttle valve mounted in a suction conduit for communicating a portion of the suction conduit upstream of the throttle valve with a portion thereof downstream of the throttle valve, and a bimetal member in the form of a spiral operatively connected to the valve element for varying the quantity of air flowing through the passage for air for idle running of the engine in accordance with changes in the temperature of the engine. The end of an outermost convolution of the bimetal member is a fixed and the end of an innermost convolution of the bimetal member is a movable member, and a bimetal shaft connected to the movable end of the bimetal member for transmitting a displacement of the bimetal member to the valve element is journalled by a bearing means, thereby inhibiting vibration of the bimetal member to prevent variations in the quantity of air flowing through the passage for air for idle running of the engine from occurring.
