PROBLEM TO BE SOLVED: To efficiently agitate a molten resin in a process of its passing through a nozzle. SOLUTION: A plurality of partition walls 17 are provided in the through-hole 9 of the main body 7 of the nozzle in such a manner that they are tilted to the axis of the main body 7 in zigzag and in alternately reverse directions. Thereby a plurality of agitating chambers 21 are formed so that they are zigzag to the axial direction of the main body 7 and deflected alternately therefrom. A plurality of thin holes 17d are so formed in each partition wall 17 as to pierce it and thereby the adjacent agitating chambers 21 are made to communicate with each other. COPYRIGHT: (C)2004,JPO
