Abstract
A fuel injector 100 includes a nozzle member 60 having a fuel passage 60a leading to an injection port 60b; a valve main body 51 adapted to reciprocate for opening and closing the fuel passage 60a; an elastic portion 56 elastically deformable in closing the fuel passage 60a by movement of the valve main body 51 in a closing direction, the elastic member being attached to one of the nozzle member 60 and the valve main body 51 and adapted to be abutted against the other of the nozzle member 60 and the valve main body 51 to close the fuel passage 60a by moving the valve main body 51 in the closing direction; and a stopper 70 adapted to restrict movement of the valve main body 51 in the closing direction by being abutted against the valve main body 51, the stopper 70 being formed of material different from the nozzle member 60.
