る。In this structure, the screw-type connector is temporarily fixed to the connector temporary fixing portion provided on the lower cover. In this case, the screw-type connector is fixed to the connector temporary fixing portion by inserting the cylindrical main body into the recess and inserting the temporary locking projection into the temporary locking hole. In addition, the column is inserted into the insertion hole of the cylindrical body, and the rotation-preventing protrusion is inserted into the rotation-stopping concave portion. As a result, the screw-type connector is positioned in the rotational direction with respect to the connector temporary fixing portion. Then, the connection box main body is dropped into the lower cover for the screw-fastened connector, and the lower surface side of the connection box main body is covered with the lower cover. This dropping is performed so that the connector connecting portion of the connection box body faces the connector temporary fixing portion of the lower cover. In this state, the screws supported by the connection box body are screwed into the nuts of the screw-type connector and tightened. As a result, the screw-fastened connector is attracted to the connection box main body, and moves away from the connector temporary fixing portion toward the connection box main body, so that the connection box main body and the screw-fastened connector are coupled. Thereby, assembly is performed.
