Claims

[Scope of Claim for Utility Model Registration] The throttle lever 4 of the throttle valve 3 of the fuel/air mixer 1 is constructed so that it can be received by the valve-closing side stopper 5 at a position A near the fully closed valve. is fixedly installed in the mixer body 2.
In the throttle lever closing side stopper device of the air mixer, a buffer spring 6 is attached to the valve closing side stopper 5, and the buffer spring 6 is installed slightly before the throttle lever 4 is received by the valve closing side stopper 5. In the operating region B near the fully closed valve, the throttle lever 4 is provided so as to be pressed toward the valve opening side, and in the region _B1 where the amount of deflection L is small, the spring constant _K1 is small;
A throttle lever closing side stopper device for a fuel/air mixer of an engine, characterized in that a spring constant _K2 is large in a region _B2 where the amount of deflection L is large.
