Claims (1)

[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 rotary shaft and displaceable in the axial direction in conjunction with the driving means; a rotation converter that converts the axial displacement of the telescoping rod into a rotational displacement of the rotary shaft; a rotation converter fixed to the rotary shaft and displacing the rotary shaft a first member that is driven by the rotation of the rotary shaft; and a first member that is rotatably attached to the rotary shaft, contacts an adjustment screw that is movably inserted in the first member, and receives the rotational force of the first member to rotate around the rotary shaft. a second part that is rotated by the user and has an engaging part at the tip thereof;
a plunger pull-back mechanism consisting of a member; which normally receives a biasing force in the direction of closing the bypass air passage, engages with an engaging portion of the plunger pull-back mechanism, and is pulled out by receiving the pull-back force of the plunger pull-back mechanism; An operating mechanism for an idle adjustment valve for an internal combustion engine, comprising an idle adjustment valve plunger; (2) The rotation conversion unit is connected to the telescopic rod via the connection part at the lower end thereof, and includes a swing arm that is attached to the rotation shaft so as to be free to rotate, and a swing arm that is fixed to the rotation shaft and that rotates the swing arm. The operating mechanism for an idle adjustment valve for an internal combustion engine according to claim 1, further comprising a rotational drive member that rotationally drives a rotation shaft in response to rotational force of the arm.
