Why We Need a Care Movement

An automatic choking device of an electric heating type for use in an automobile engine and the like having a carburetor main body, a choke valve provided in the carburetor main body, a shaft for rotating the choke valve which is supported on the carburetor main body in a freely rotable manner, a bimetal member connected to the rotational shaft for the choke valve by means of a connecting member, and to cause the rotational shaft to rotate, when heated, to open the choke valve, heating means having an electric heating mechanism to heat the bimetal member, and a switch means to open and close a connecting circuit between the heating means and a power source for the same, in which the electric heating mechanism functions to maintain the choke valve in a substantially perfectly closed state without actuating the bimetal member when the internal combustion engine is at a low temperature level, to open the choke valve by heating the bimetal as the temperature of the engine rises with lapse of time, and to lower the temperature thereof after the bimetal is sufficiently heated to be able to open the choke valve.
