A reduction gear 15 is provided in a depression portion 14 formed on the top surface of the stationary base 11. A motor 16 having a rotational shaft 17 connected to the reduction gear is provided on the swinging base. A cable support portion 21 which is rotatably supported by means of a bearing 18 provided on an axis A is provided inside the stationary base 11. The cable support portion 21 supports cables C.
