STRUCTURE OF HEATING BODY, MANUFACTURING METHOD OF THE SAME

摘要

A structure of a heating body and a method for manufacturing the same are provided to prevent a heating unit from being extended when the heating body is heated by installing an elastic supporting unit on the heating unit. A structure of a heating body includes a tube(110), a heating unit(200), and an elastic supporting unit(210). The heating unit(200) is arranged inside the tube(110). The elastic supporting unit(210) is arranged on at least a part of the heating unit(200). The elastic supporting unit(210) give an elastic force to the heating unit(200). The elastic supporting unit(210) has a winding shape by the number of predetermined times. The elastic supporting unit(210) is arranged symmetrically with the heating unit(200). The elastic supporting unit(210) is installed on a center part of the heating unit(200).
