摘要： PROBLEM TO BE SOLVED: To provide an air-fuel mixture correcting device of a constant vacuum type carburetor, enabling a vehicle to start and travel just after starting at the low temperature and in warming-up operation, in the constant vacuum type carburetor having an automatic starter. SOLUTION: This constant vacuum carburetor has the automatic starter S and a temperature correcting device T. The temperature correcting device T is formed by arranging a control valve element 8 for controlling opening-closing of a negative pressure control hole and an air control hole 6 by a thermosensible reactive member 87 in a control valve guide cylinder 4 for opening an atmospheric hole 5, the negative pressure control hole 7 and the air control hole 6. A main air jet for constituting a main fuel system of the constant vacuum type carburetor is formed in parallel by a first main air jet 1 and a second main air jet 11 connected to a downstream side main air passage 2. The atmospheric hole 5 is connected to the atmosphere, and the negative pressure control hole 7 is connected to a pressure receiving chamber 60, and the air control hole 6 is connected to the second main air jet 11. At the low temperature, the control valve element 8 cuts off the air control hole 6 and the atmospheric hole 5, and communicates the negative pressure hole 7 with the atmospheric hole 5. The control valve element 8 communicates the air control hole 6 with the atmospheric hole 5, and also cuts off the negative pressure control hole 7 and the atmospheric hole 5 in response to a temperature rise.
