Claims

[Scope of Claim for Utility Model Registration] The flow regulating valve 2 of the air/fuel mixer 1 of the spark ignition engine E is operated by a governor spring 4 via a governor lever 3 to increase the air-fuel mixture by a spring force and by detecting the engine rotation speed. In a governor device for a spark ignition engine configured to be able to be controlled by a force unbalanced with the governor force to force the air-fuel mixture to decrease by the device 5, the governor lever is within the swing range A of the governor lever 3 and swings to the increase side. A maximum increase position limiting stopper 6 is attached at a position where it can come into contact with the maximum increase position B, and the maximum increase position limit stopper 6 is configured to be adjustable forwards and backwards in the direction of increase and decrease of the governor lever 3, so that the governor lever 3 swings beyond the maximum increase position B. A governor device for a spark ignition engine, characterized in that the governor device for a spark ignition engine is configured such that the minimum fuel increase position limiting stopper 6 prevents this from occurring.
