PROBLEM TO BE SOLVED: To simplify work for establishing armature displacement quantity of an injector 1. SOLUTION: A shim 8 is arranged to be exposed to an outside by the injector 1 and is gripped in an axial direction by a retaining nut 7 and a body 19. Consequently, the shim 8 can be taken out to an outside by loosening a retaining nut 7 in one axial direction and the shim 8 can be built in from the outside. Also, armature displacement quantity varies according to rotary quantity of the retaining nut 7 since a stopper 6 and the retaining nut 7 rotate as one body. Consequently, it is not necessary to release thread engagement of the retaining nut 7 and a main body 2 in replacement of the shim 8, and armature displacement quantity is automatically established according to rotation quantity of the retaining nut 7. As a result, work for establishing armature displacement quantity is simplified. COPYRIGHT: (C)2008,JPO&INPIT
