Claims

[Scope of utility model registration request]

(1) A generally cylindrical rotary throttle valve whose end protrudes from the carburetor body and is accommodated in the carburetor body and has an operating lever fixed to the protruding end, which is caused by rotation of the rotary throttle valve. a cam mechanism for regulating the displacement of the rotary throttle valve in the direction of its rotation center axis; 1. The cam mechanism includes a plurality of cam surfaces provided on a portion of the carburetor body facing the operating lever, each of which extends in parallel with each other in the circumferential direction of the rotary throttle valve, and each of which extends in a different direction. a plurality of cam surfaces having an inclination, a cam follower attached to the operating lever, and a cam follower attached to the operating lever in a radial direction of the rotary throttle valve so that the cam follower can be selectively engaged with the plurality of cam surfaces. and means for adjusting the position of the rotary throttle valve.

(2) The rotary throttle type carburetor according to claim (1), wherein the plurality of cam surfaces are continuous with each other in the radial direction of the throttle valve.
