PURPOSE:To enable replacement of a part of which resin adheres easily by fitting replaceable slide slit cover and nozzle plate to a nozzle slit forming portion and the bottom of a nozzle, respectively. CONSTITUTION:A nozzle plate 11 has both bending skirt portions 11a opposed to each other and bent inward, and inward bending portions 11b are fitted in small grooves 17 of a U-shaped or C-shaped guide member 16 having a pair of fitting small grooves 17 corresponding to the skirt portions to assemble a nozzle device. In this case, the nozzle plate 11 can be easily separated from the guide member 16. On the other hand, a slit cover 19 is slidably fitted to a small groove 18 in such a manner as to cover the edge portion of a housing 12. Accordingly, the slit cover 19 can be also separated. |
