アイドル制御装置。[Scope of Claim for Utility Model Registration] (1) A vehicle equipped with a cooling circuit that is driven by an engine and includes a variable capacity compressor that has a built-in capacity adjustment mechanism that can adjust the discharge capacity by itself according to the heat load. The idle control device comprises: an engine rotation speed detection means for detecting the engine rotation speed; a valve opening means capable of opening a throttle valve of a fuel carburetor based on an idle position; An idle control device for a vehicle, comprising an idle control means that maintains an idle rotation of an engine constant by adjusting it in inverse proportion to fluctuations in rotation speed. (2) The vehicle idle control device according to claim (1), wherein the opening degree of the throttle valve is changed in stages by the valve opening means.
