PURPOSE:To carry out heat radiation of a material efficiently even if the material is an electrothermal part with a large rating capacity by composing a part installation frame with a metal such as an aluminum die cast which has high heat radiation effect and installing an elastic fitting part to fit a part elastically in one side of it. CONSTITUTION:A part installation frame 1 is formed using aluminum die cast, a heat radiation part 2 of a heat generating electric part is installed integrally therein and a light modulation apparatus 5 is installed there. Also, a part space 3 for installation of another part is formed, a switch, etc., is installed therein, an adapter 4 for installation of an elastic part closely to the installation frame 1 is installed in one side of the space 3 by plastics, and an elastic fitting part 9 is installed therein. Further, an installation hole 10 for installation of the frame 1 in a buried box, a surface 11 for installation of a light modulation apparatus, and a surface 12 for installation of a switch are formed in the installation frame 1, and fitting holes 13 to bind pawls in the switch side are formed in the installation side of the adapter 4 and in the opposite side, respectively. |
