Thus, with the unauthorized tool, the first elastic claw (163) engaged with retaining in the space portion (155) of the attached portion (152) is deformed inward to remove the sealing pin (16), Unauthorized actions such as removing the board case (14) from the base bracket (15) can be prevented.

[0055] After inspecting the electronic component (81) of the main control board (8) after fixing the board case (14) to the base bracket (15), first, the symbol (137) "B" Each of the cut portion (136) of the corresponding third sealing portion (134) and the cut portion (18a) connected to the sealing pin (16) is cut with a tool such as a nipper, and the third seal is cut. The stopper (134) is separated from the second case body (13), and the sealing pin (16) is separated from the connecting plate (18). Thereafter, the board case (14) can be removed from the base bracket (15) by loosening the screw (19).

[0056] After the substrate case (14) is removed from the base bracket (15), the cut portion (136) and the sealing pin (136) of the second sealing portion (133) corresponding to the symbol (137) "A" Cut the cutting parts (18a) of 16). As a result, the second sealing portion (133) and the sealing pin (16) corresponding to the symbol (137) “A” are separated from the first case body (12), so that the substrate case (14) is opened. The main control board (8) can be taken out and inspected. [0057] When the main control board (8) is inspected by an external inspection organization, the second sealing portion (133) corresponding to the symbol (137) "F" is removed by the sealing pin (16). Then, it is transported to an external inspection organization while being fixed to the first sealing portion (124) by the sealing pin (16). As a result, the substrate case (14) is not tampered with during the transfer of the substrate case (14).

[0058] After the inspection, the substrate case (14) is discarded. Then, an unused board case (14) is prepared, the main control board (8) is accommodated in the board case (14), and the second sealing part (133) corresponding to the symbol (137) “A” is provided. It is sent back in a state of being fixed to the first sealing portion (124) by a separately prepared sealing pin (16).
