<p>PROBLEM TO BE SOLVED: To obtain a satellite broadcasting receiving down converter having a detent structure with an excellent workability, which is produced at a low cost, by providing a case part provided with two protrusions in a case, which are brought into contact with a inner wall of the cylinder case. SOLUTION: An output connector 4 is attached to a position separated from a center axis of the cylinder case 6. An end board 3 arranged at the end of the case 1 is functioned as an attachment base of the output connector 4. The protrusions 5 brought into contact with the inner wall of the cylinder case 6 are arranged at respective positions after rotation in the circumferential direction by +90 degrees±about 30 degrees and -90 degrees±about 30 degrees from the cylinder case inner wall position being most close to the output connector 4 in the peripheral edge of the end board 3. The output connector 4 is attached by separation from the center axis of the cylinder case 6 so that the rotation is stopped-off since one of the protrusions 5 is hit against the cylinder inner wall even if the case 1 is about to be rotated with the output connector as a center.</p> |
