PURPOSE:To make a pivotal body arrageable at will and improve the setting work efficiency of the pivotal body as well as to make a carburetor miniaturizable as a whole, by having each pivotal body supported on a supporting member to be detachably installed in a carburetor body. CONSTITUTION:Owing to a supporting member 13 being locked detachably to a carburetor body 1, almost all of forming elements are opened or closed and driven by a manual chole device Mc being supported by the supporting member 1. A valve shaft 16 supported by the carburetor body 1 and a pivot 25 having a parallel axis are rotatably supported on the supporting member 13 with both their end parts projected to both sides, while a link lever 19 is locked to an end part at the side of the carburetor body 1 of the pivot 25. A link lever 26 is locked to the end part projected out of the carburetor body 1 of the valve shaft 16, and both link levers 19 and 26 are coupled together via a link bar 27. Therefore, the valve shaft 16 pivots according to the pivotal action of the pivot 25 whereby a choke valve 8 is opened or closed. Doing like this, arrangement of each pivotal body will not be restricted at all from the standpoint of manufacturing problems and, what is more, work efficiency is improved. |
