<p><P>PROBLEM TO BE SOLVED: To smoothly move a shaft displacement absorption washer 17 without being affected by abrasion by reducing the horizontal displacement of the shaft displacement absorption washer 17 in a lateral direction when a fuel injection valve 1 is assembled to the inside of the cylinder head fitting hole 3 of an engine 2. <P>SOLUTION: The fuel injection valve 1 is pressurized with respect to the fitting hole 3, pressurizing force is received by the shaft displacement absorption washer 17, and the washer 17 is positioned in the inclined portion 15 of an intermediate diameter portion between a small diameter portion 9 and the intermediate diameter portion 10. A first stage 25 having a washer receiving portion 26 is provided between the small diameter hole portion 20 and intermediate diameter hole portion 21 of the fitting hole 3. The washer receiving portion 26 has a substantially plane portion so that the shaft displacement absorption washer 17 is substantially moved in a direction perpendicular to the axial centers J1, J2 of the fuel injection valve 1. Thereby, even if the fuel injection valve 1 is inclined, it is possible to reduce the displacement of the shaft displacement absorption washer 17 and to smoothly move the shaft displacement absorption washer 17. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
