Claims

[Scope of utility model registration request]

A fixed shaft, a cylindrical rotor made of a magnetic member that is rotatably supported by the fixed shaft, and a bypass air passage that is attached to one end of the rotor and is rotationally driven by the rotor, bypassing the intake throttle valve of the engine. a valve body that changes the cross-sectional area of the passage; a spring that biases the valve body in one of the valve-closing direction and the valve-opening direction; An idle speed of an internal combustion engine, comprising a coil for rotating the valve body against the biasing force of the spring on the other side of the valve direction, and controlling the air flow rate of the bypass air passage by changing the amount of current applied to the coil. In the control valve, the rotor is formed of a porous member subjected to plastic processing, one end of the rotor on the valve body side is supported by a fixed shaft via a bearing, and the other end of the rotor is impregnated with a lubricant. An idle speed control valve for an internal combustion engine, characterized in that the other end is supported by the fixed shaft.
