PROBLEM TO BE SOLVED: To provide a nozzle for an injection molding machine which can stably form various marble patterns. SOLUTION: A nozzle body 10 is connected to a main injection device 51 through an end cap 30, and connected to a subordinate injection device 52 through a connection block 40. The nozzle body 10 is composed of a casing 11 and a core 12, and a discharge opening 13 is formed at the tip of the casing 11. An annular channel (the first channel 15) is formed between the outside surface of the core 12 and the inside surface of the casing 11, and a through hole (the second channel 16) is formed at the center of the core 12. The first channel 15 is ended on the central axis in the vicinity of the tip of the nozzle body 10, and connected to the discharge opening 13. The second channel 16 is bent to deviate from the central axis in the vicinity of the tip of the core 12, opened in the side of the core 12, and joined to the first channel 15. COPYRIGHT: (C)2003,JPO
