Abstract
A first and second electric members respectively having electrical connection portions are electrically connected in a state that mutual positions are regulated by guide pins, and fastening screws which are inserted through fastening screw insertion holes of the second electric member are screwed into screw holes for fastening of the first electric member, and thereby the first and second electric members are fastened. At least one of the screw holes for fastening has large-diameter portions into which the guide pin is detachably inserted, and small-diameter portions equipped with female screw portions. The female screw portions are not arranged in the large-diameter portions, and inner diameters of the large-diameter portions are larger than root diameters of the female screw portions, and outer circumferential surfaces of the fastening screws which are screwed with the female screw portions and inner circumferential surfaces of the large-diameter portions are not in contact with each other.
