PROBLEM TO BE SOLVED: To speed up the temperature rise of a carburetor by heating of a PTC heater in a heating device attached to a carburetor. SOLUTION: An electrode plate 7 and a conductive spring 8 are received in a recess 6 of an insulating property heat insulator 5. A fixed plate 9 adhered to the lower surface of a PTC heater 1 is contacted with a spring 8, and the upper surface of the PTC heater 1 is joined directly with a conductive housing of a carburetor to be heated. Also, the fixed plate 9 is provided with projections 10 engaging with the recess 6 to prevent the PTC heater 1 from jumping out when it is not attached to the carburetor. The circuit of the PCT heater 1 having pressure contact spots fewer than conventional ones is formed by joining the carburetor with the heat insulator 5 to electrify the PCT heater 1 and heat the carburetor. |
