<p><P>PROBLEM TO BE SOLVED: To provide a screw tightening configuration in a liquid ejection head holding mechanism, which is capable of preventing the displacement of the liquid ejection head, when screwing and tightening a component of the mechanism, concerning the liquid ejection head holding mechanism for holding the liquid ejection head. <P>SOLUTION: The screw tightening configuration includes a first annular projection 59, which is projectingly arranged toward a holding frame at an opposing portion against the holding frame in an axial direction Z of a screw 28 in a flow path forming member 30 tightened by the tightening force of the screw 28 for the holding frame for holding the liquid ejection head, and which is collapsed and deformed by a torque received from the screw 28 and a reaction force received from the holding frame side upon tightening the screw 28. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
