Claims

[Scope of utility model registration request]

In a device for adjusting the target engine speed, which is included in an idle engine speed control device that controls the engine speed during idle operation so as to approach a target engine speed set in advance according to operating conditions, the idle engine speed is controlled. Means for generating a signal to increase the target rotational speed by minute rotations each time an external terminal is manually grounded in a control unit with a built-in circuit; means for generating a signal that decreases the number of rotations, and a means for storing signal data generated by grounding operation of the signal generating means;
1. A target rotation speed control device for an idle rotation speed control device for an internal combustion engine, comprising means for increasing or decreasing a target rotation speed during idling operation based on data stored in the storage means. ,゛
