PURPOSE:To prevent moisture in air from icing and adhering to a throttle valve or the like by a method wherein a heating body is provided on an insulator interposed between the throttle valve section of suction air path and suction air manifold and the heating body is pushed to the side of the throttle valve by a resilient body. CONSTITUTION:A heat radiating plate 25 is abutted against the lower surface of flange 23 for the throttle valve section 11 of a carburettor and the heating body 27 is attached to the lower surface of the heat radiating plate 25. A mounting hole 33 is provided below the upper inserting hole 29 of the insulator, into which the heating body 27 is inserted, and the resilient body 31, such as a spring or the like and which is energizing the heating body 27 toward upper direction or the side of the flange section 23, is mounted in the mounting hole 33. When the key switch of the internal-combustion engine is put ON, an electrode plate 37 is conducted and the heating body 27 is heated through an electroconductive member 39 and an electrode 43. Heat from the heating body 27 is transferred to the heat radiating plate 25 and is transferred further to the throttle valve section 11 through the flange section 23. According to this method, the moisture in air may be prevented from icing and adhering to the throttle valve 17 or the like. |
