<p>PROBLEM TO BE SOLVED: To contrive to save space to be occupied with heating components to be incorporated into a junction box by evading the adverse influence of the heat of the heating components on control components thereby enabling the heating and control components to be mounted on the same board. SOLUTION: Heating components such as a relay 14 and the like are mounted on a board 13 through a relay block, while a pattern prohibiting part A is provided between control components and the relay 14. An upper cover 11 which comprises a junction box 10 is provided with an air convection-proof wall 19 inside the cover to be abutted against a mounting prohibiting area B of the pattern prohibiting part A.</p> |
