PURPOSE:To prevent the hollow yarn from being cut off with the penetrating water flow or washing liquid flowing to reverse direction by inserting a ring-shaped component having a protrusion for preventing direct transfer of the flow into the end of the case and positioning the said protrusion between the nozzle for penetration flow and the hollow yarn. CONSTITUTION:A ring-shaped component 9 having the outer diameter smaller than the inner diameter of the cylindrical case 2 and also having a protrusion 6 for preventing direct transfer of the flow into one end 7 of the case 2, and the said protrusion 6 is positioned between the nozzle 8 for penetration flow and the hollow yarn bundle 5. Another similar shaped ring is also inserted into the other end of the case 2 and, after both ends of the hollow yarn bundle 5 are inserted into each of the said ring-shaped components respectively, the space between each of the yarn ends of the hollow yarn bundle 5, the space between the ends of hollow yarn bundle and the ring-shaped components and the space between the ring-shaped components and the end of the case 2 are sealed with adhesive. The penetrating flow from the hollow yarn bundle 5 to the nozzle 8 for penetrating water and the washing flow from the penetrating nozzle 8 to the hollow yarn bundle 5 are interfered with the protrusion 6 and go round about to prevent the hollow yarn bundle 5 from being affected by the force of flow.
