PROBLEM TO BE SOLVED: To provide a fuel injection valve which reduces changes of fuel injection characteristics when it is mounted on an engine. SOLUTION: An end 54 of a housing member 50, which forms a magnetic circuit on the side opposite to a holder, is not secured on a cylindrical member 11, so that the end 54 of the housing member 50 can be reciprocatingly moved relatively in the axial direction of the cylindrical member 11. Accordingly, when an injector 10 is mounted on the engine, even if the axial load acts on the housing member 50, deformation of the housing member 50 caused by the load is not transmitted to the cylindrical member 11. Consequently, before and after mounting the injector 10 on the engine, a change in distance between a fixed core 43 and a movable core 44 is reduced. Therefore, it is possible to reduce the changes of the fuel injection characteristics of the injector 10. COPYRIGHT: (C)2005,JPO&NCIPI
