PURPOSE:To prevent the thermal deterioration of electric parts in a body and prevent the fluctuation of position of a heating body by a method wherein a rise-up section, provided with a plurality of notches on the upper surface around the mounting holes of the body, is provided and the positioning fitment of a heating plate receiver is engaged with the notch while the heating plate receiver is bent to the side of lower surface around the mounting holes of the body to attach it to the body. CONSTITUTION:A heater unit, integrating the heating body 12, support fitments 14, 15 and a liquid receiving pan 20, is dropped into the mounting hole so that the positioning fitment 10, secured to the rise-up section 6 at the peripheral rim of the heating plate receiver 5, is engaged with the notch 3, provided at the rise-up section 4 of the body 1, and the retaining fitment is bent to the side of lower surface around the mounting hole of the body 1, whereby said unit is attached to the body 1. A gap is formed between the rise-up section 4 of the body 1 and the peripheral rim section 7 of the heating plate receiver 5 and hot air in the body 1 flows out of the body 1 through the gap, therefore, the electric parts, equipped in the body 1, may be cooled effectively. Further, the heating plate receiver 5 will never be turned with respect to the body 1 even if a shock or the like is applied to the heating plate receiver 5. |
