Flexes freely and covers the head of the screw 17, so its upper base
A good insulation state can be maintained between the lead wire 20 attached to 16 and the lead wire 20. Further, in the work of connecting the external lead wire 20, the terminal plate 25 is fastened from the lower mounting portion base 16C to the middle and upper stages in sequence with one screw. In this case, the insulation attached to the terminal plate 25 is insulated. The shielding plate 31A of the member 31 is kept in an upright state until connection work is performed on the mounting portion base above it, so that there is no problem in screwing. Further, the shielding plate 31 previously attached when the connection work is performed in the attachment base at the upper portion, for example, 16B, bends as shown in the figure to cover the screw head.
