記載の内燃機関用気化器。[Scope of Claim for Utility Model Registration] 1. At least one passage is provided that opens in the internal combustion engine air cleaner and extends from the air cleaner to the intake passage on the downstream side of the carburetor throttle valve, and the at least one passage is connected midway through the vaporizer. 1. A carburetor for an internal combustion engine, characterized in that a temperature sensing valve is provided in the opening in the air cleaner, the temperature sensing valve communicating with a float chamber of the air cleaner and opening and communicating the passage when the temperature is higher than a set temperature. 2. A passage is provided that opens in the internal combustion engine air cleaner and extends from the air cleaner to the intake passage on the downstream side of the carburetor throttle valve, and the passageway is communicated with the float chamber of the carburetor to maintain a temperature higher than the set temperature. 2. The carburetor for an internal combustion engine according to claim 1, wherein the opening in the air cleaner is provided with a temperature sensing valve that opens and communicates the one passage. 3. Two passages are provided that open into the internal combustion engine air cleaner and extend from the air cleaner to the intake passage on the downstream side of the carburetor throttle valve, and at least one of the two passages is connected to the float chamber of the carburetor. 2. The carburetor for an internal combustion engine according to claim 1, wherein the opening in the air cleaner is provided with a temperature sensing valve that communicates with the two passages and opens and communicates the two passages when the temperature is higher than a set temperature.
