PURPOSE:To obtain stable particles-forming performance without depending on temperature by connecting a nozzle portion wherein a nozzle plate is rigidly connected to a mounting part and connecting a vibrating portion to generate uniform ink droplets to a liquid chamber body. CONSTITUTION:A nozzle plate 7 with an orifice 8 is inserted into the nozzle hole 9a of a mounting part 9 and welded by lasers to form an integrally stiff-connected nozzle portion. The stiff-connected nozzle portion is connected through an O-ring to the liquid chamber body 10 by a parting screw 11. A vibrating plate 14 welded with a piezo-vibrating element 15 is connected by welding or screw to the opposite side of the nozzle of the liquid chamber bodt 10. The variation in the efficiency of the ink jet vibration system with the change of temperatures can thus be suppressed and stable particles-forming performance without depending on temperature can be obtained. Since the nozzle plate is rigidly connected with the mounting part, a dispersion in assembling work can be eliminated. |
