PURPOSE:To perform the fixing of a circuit board to a casing and grounding of the casing simultaneously and facilitate fitting work, by inserting caulking pieces extending from a casing into supporting holes made in a circuit board, and caulking these pieces. CONSTITUTION:Caulking pieces 28 extending from a casing 1 are inserted into supporting holes 23 made in a circuit board 25. Then by caulking these pieces 28 the circuit board 25 is mechanically supported by the casing 1 and besides grounding sections 24 are electrically connected with the casing 1 through the medium of the caulked pieces 28. And when the casing 1 is electrically connected to the printed wiring of the circuit board 25, this is grounded to the power source side and the casing 1 is grounded consequentially. These procedures perform the fixing of the circuit board 25 to the casing 1 and the grounding of the casing 1 simultaneously. |
