The two molded products 3, 4 are fixed by the screw 5 with the hole 3b of the molded product 3 and the hole 4b of the molded product 4. 2 is t
= Satellite broadcast pack covered with an iron plate of = 0.8, 2a is a heat dissipation hole provided at the top of satellite broadcast pack 2, 2b is a heat dissipation hole provided at the bottom thereof, and 3 has electrical insulation properties. A plastic molded product 3a is a projection of the molded product 3 and is fitted into a fixed position of the hole 2b of the satellite broadcast pack 2. 3b is the hole 1a of the character multiplex pack 1 after the above-mentioned fixed position hole 2b and the convex portion 3a are fitted.
A hole for fixing the screw 5 from the lower part to the hole 1a through the hole 3b, a hole 3c into which the screw portion of the screw 5 is fitted, 4 a plastic molded product having an L-shaped insulation characteristic, and 4a a molded product 4 Are fitted to the fixed positions of the holes 2a of the satellite broadcast pack 2 at the projections of 4b
Is a hole for fixing a screw by aligning the hole 1a of the character multiplex pack 1 with the hole 3c of the molded product 3 after fitting the hole 2a and the convex portion 4a at the above-mentioned fixed positions, 5 is a metal screw, and 6 is a character. A television receiver with a built-in multiplex pack 1 and a satellite broadcast pack 2; 7, a cathode ray tube; 7a, a printed board at the neck of the cathode ray tube 7; 8, a wiring board of the television receiver 6; The cover, 9a is a hole for fixing the character multiplex pack 1, 9b is a hole for fixing the satellite broadcast pack 2, and 9c is a hole for fixing the back cover 9.

In the present embodiment, first, after the convex portion 3a of the molded product 3 is fitted into the hole 2b at a fixed position of the satellite broadcast pack 2, the convex portion 1b of the character multiplex pack 1 is fitted to the upper portion of the molded product 3, While aligning the hole 3c with the hole 1c, align the other hole 1a with the hole 3b, insert a screw into the hole 3b, tighten the screw into the hole 1a, and fix the screw. Next, the convex part of the molded product 4
