PURPOSE:To prevent the cutting of hollow yarn due to a water current by fixing a specified cylindrical body to the inside of a case and arranging a wall for preventing the direct transfer of the water current between a nozzle of permeated water and a bundle of hollow yarn which is formed on the cylindrical body and thereby making a by-pass for the current of permeated water or washing liquid. CONSTITUTION:A cylindrical body 4 which consists of a plastic molded form or the like and is provided with both many through-holes 7 for passing a water current and a wall 8 for preventing the direct transfer of the water current is fixed to the inside of a cylindrical case 1. On this occasion, a path 6 of the water current is formed between the case 1 and the cylindrical body 4 and an interrupting wall 8 is positioned in a nozzle 5 part of permeated water in the drum part of the case. A bundle of hollow yarn is inserted into the inside of the cylindrical body 4 and bonded with an adhesive 3 and sealed. By such a way, the current of permeated water flowing to the nozzle 5 from the bundle of hollow yarn or the current of washing liquid flowing to the reverse direction is interrupted and by-passes, thereby the cutting of hollow yarn is prevented because the force due to these currents does not directly affect the bundle of the hollow yarn.
