Claims

[Scope of utility model registration request]

A means for determining whether or not the operating range is in which feedback control of the air-fuel ratio is performed, and a means for making the actual air-fuel ratio match the stoichiometric air-fuel ratio based on a signal from a sensor that detects the actual air-fuel ratio when this is determined. a first mechanism that rotates in conjunction with an accelerator pedal, a second mechanism that rotates in conjunction with a throttle valve, and a mechanism that connects both mechanisms to each other. a means for displacing the position where the coupling mechanism is attached to one of the rotating mechanisms in the rotational radial direction; a switch that can be switched according to the driver's will; and a means for determining whether the switch has been switched. , means for setting the rotation ratio of the second rotation mechanism to the first rotation mechanism to be small when this is determined and the air-fuel ratio is in the operating range in which feedback control is performed; A throttle valve control device for an engine, comprising means for outputting a signal to the displacement means.
