Abstract:
A fuel injector comprises a movable element, a seat contact surface formed at one end of the movable element, a nozzle member having a valve seat. The seat contact surface of the movable element is in contact with and seated on at the time of valve closing. A nozzle holder portion holds a periphery of the nozzle member. A plastic deformation portion is formed by engaging one of a part of the nozzle member and a part of the nozzle holder portion in the other one of the part of the nozzle member. The nozzle member and the nozzle holder portion are joined by welding.
