Claims

[Claims for Utility Model Registration] (1) An idler that has a plurality of intake passages, a bypass air passage is provided for each intake passage, and an idler that throttles the amount of air flowing through the bypass air passage. An operating mechanism for an idle adjustment valve disposed around a throttle body in which an adjustment valve is disposed, the mechanism comprising: a rotating shaft disposed on a side surface of the throttle body in which the idle regulating valve is disposed; and a side intersecting the rotating shaft. a telescoping rod disposed on the shaft, which is displaceable in the axial direction in conjunction with the driving means; the telescoping rod is pivotally connected to the telescoping rod via a connecting portion at the lower end, and is attached to the rotating shaft so as to be free to rotate; Converts the axial displacement of a telescoping rod, which is made up of a swinging arm, and a rotating shaft drive member, which is fixed to the rotating shaft and rotates the rotating shaft in response to the rotational force of the swinging arm, into rotational displacement of the rotating shaft. a rotation conversion unit that rotates in conjunction with a rotation axis and has an engaging portion at its tip; a plunger retraction mechanism that normally receives a biasing force in the direction of closing the bypass air passage; An operating mechanism for an idle adjustment valve for an internal combustion engine, comprising: a plunger of an idle adjustment valve that engages with an engaging portion of a plunger pullback mechanism and is pulled out in response to a pullback force of the plunger pullback mechanism. (2) In the connecting part, the lower end of the swinging arm is folded back into a U-shape, and the swinging shaft is attached to the swinging shaft via a bearing so that it can swing freely, and a through hole is formed in the center of the swinging shaft. 2. The operating mechanism for an idle control valve for an internal combustion engine according to claim 1, wherein a threaded portion of the telescopic rod is inserted into the through hole and clamped by tightening nuts from both sides thereof. (3) The operating mechanism for an idle adjustment valve for an internal combustion engine according to claim 1 or 2, wherein an adjustment screw is interposed between the swing arm and the rotation shaft drive member. (4) The operating mechanism for an idle control valve for an internal combustion engine according to claim 1, wherein a wire is used in place of the telescoping rod, and the wire is fixed to the lower end of the swing arm.
