PURPOSE:To arrange the constitution that screw tightening work may be performed from the rear(bottom) side of an apparatus and steady screw tightening may be executed by accompanying a hand to a screw by separating the apparatus with an outside case as a bottom cover. CONSTITUTION:The bottom face of an outside case 1 is cut off and opened largely at a part corresponding to a connection terminal part 3 so that the part of an internal lead fastening screw 303 of a terminal fixture 301 may be exposed and after electric connection of an internal element 5 with an internal lead fastening screw 303, this bottom cover is closed and connected and fixed using a screw hole 104 at the outside case 1. Before connecting the bottom cover to the outside case 1 a connection lead from the internal element 5 is connected electrically to each terminal fixture 301 at the connection terminal part 3 by means of the internal lead fastening screw 303. Hereby, when fastening it with a driver 7, since both hands can be used effectively, the fastening of the fastening screw 303 becomes very simple and easy work. |
