<P>PROBLEM TO BE SOLVED: To provide a discharge structure capable of surely closing a discharge port of a nozzle member after a liquid is discharged even when the discharge port is deformed or elastic force of the port is decreased due to fatigue of the nozzle member, in the discharge structure wherein the discharge port of an elastic nozzle member is opened by the discharge pressure of the discharge liquid against the elastic force. <P>SOLUTION: In the discharge structure, the discharge port 22 formed at the front edge part of the nozzle member 20 deformable elastically is provided while the port can be opened by the pressure of the discharge liquid against the elastic force, wherein an elastically deformable auxiliary member 30 to force in the direction closing the discharge port 22 is provided in the nozzle member 20. <P>COPYRIGHT: (C)2010,JPO&INPIT |
