PURPOSE:To accurately maintain the dimensional accuracy of an electrode or the like by pressing and holding a spring member tightened with a head body to an electrode holder having a hole for inserting the end of an ink jet head. CONSTITUTION:A nozzle 12 provided at the end of an ink jet head 11 is inserted into a hole 13a of an electrode holder 13 for holding an electrode 14 or the like. A flange 16 formed at the head 11 body is held at a spring member 15 formed of a spring wire engaged with a part 15a at the projection 17a of a hanger member 17. The ends 15b, 15c of the member 15 are engaged with the projections 17b, 17c, and the head 11 is pressed to the holder 13. In this manner, the mounting and dismounting of the ink jet heat can be facilitated. Then, it is not necessary to adjust the position of the nozzle, thereby remarkably improving the workability. |
