ねじ嵌合により進退自在に連結され、モータが駆動され
るとバルブシャフトが出入りしてバルブシートとバルブ
間のすき開面積が変化し、アイドル回転数が変化する。A step motor is used as the valve drive unit in this device, and the rotor center of the motor and the valve shaft are connected by screw fitting so that they can move forward and backward, and when the motor is driven, the valve shaft moves in and out to connect the valve seat and valve. The gap area between them changes, and the idle speed changes.

のいずれかに微小すき間を設け、組付けを容易にしてる
。The rotor described above is supported by rolling bearings at two locations: a rotor end closer to the valve and a rotor end farther from the valve. In this case, the rotor end of the rolling bearing on the valve side is press-fitted into its inner ring, and the outer ring is fixed to the housing, so press-fitting the other rolling bearing into both the inner and outer rings is difficult to assemble due to the structure of the valve. It becomes very difficult. Therefore, a small gap is usually provided on either the inner ring side or the outer ring side to facilitate assembly.
ところが、上記のバルブは内燃機関に組付けられるため
、内燃機関の作動中はたえず振動を受けることになる。However, since the above-mentioned valve is assembled into an internal combustion engine, it is constantly subjected to vibrations during operation of the internal combustion engine.
その結果前記の微小すき間において赤さび状の摩耗粉が
