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 shaft and displacing in the axial direction in conjunction with the driving means; a rotation converting section that converts the axial displacement of the telescoping rod into a rotational displacement of the rotating shaft; a plunger pull-back mechanism that rotates and has an engaging portion at its tip; a plunger of an idle adjustment valve that engages with the engaging portion of the plunger pull-back mechanism and is pulled out in response to the pull-back force of the plunger pull-back mechanism; An idle adjustment mechanism for an internal combustion engine, comprising: a rotary shaft adjustment mechanism in which an arm extension part is attached to a shaft, and an adjustment screw rod that takes a reaction force against a throttle body is brought into contact with the arm extension part; Valve operating mechanism. (2) The operating mechanism for an idle control valve for an internal combustion engine according to claim 1, wherein the drive means interlocked with the telescoping rod is a heat sensitive mechanism containing a heat sensitive substance. (3) The operating mechanism for an idle adjustment valve for an internal combustion engine according to claim 1, wherein the drive means interlocked with the telescoping rod is a lever. (4) The plunger retraction mechanism includes a first member that is fixed to the rotating shaft and follows the rotation of the rotating shaft, and a first member that is rotatably attached to the rotating shaft and rotates around the rotating shaft in response to the rotational force of the first member. The operating mechanism for an idle adjustment valve for an internal combustion engine according to any one of claims 1 to 3, comprising a second member that is moved. (5) The operating mechanism for an idle adjustment valve for an internal combustion engine according to claim 4, wherein an adjustment screw is interposed between the first member and the second member.
