摘要: Coaxial infusion pipes are disposed in a fixed shaft body and the ends of the pipes pass into a rotary shaft body. The fixed shaft body and the rotary shaft body are rotatably joined by bearings. Packings are provided inside the rotary shaft body in correspondence with the pipes. Only lip portions of the packings are in sliding contact with the pipes. The sliding resistance between the infusion pipes and the packings as seal members is low, and the rotary shaft body can rotate extremely lightly and with high precision.
