PROBLEM TO BE SOLVED: To form a meniscus of dye without complicating a manufacture method so that the dye can fly sufficiently at a dye fly part and feed the dye to the dye fly part without interruption. SOLUTION: An end edge 3a of a lid 3 is projected at the side of a dye fly part 6 further from an end edge 2a of a diaphragm 2 forming a branch path 8 of a supplied dye 7. A distance C between the end edge 2a of the diaphragm 2 and a center line C1 of the dye fly part 6 and a distance B between the end edge 3a of the lid 3 and the center line C1 of the dye fly part 6 hold a relationship C>=B, whereby the end edge 3a of the lid 3 is positioned in the vicinity of the dye fly part 6. A good meniscus is accordingly maintained, and the dye 7 of an amount necessary for the fly is retained at the dye fly part 6. |
