Abstract
A fuel injector is provided. A movable iron core is provided relatively displaceable to a valve body. A fixed iron core is opposed to the movable iron core. A first spring member energizes the valve body in a valve closing direction. A second spring member energizes the movable iron core in a valve closing direction. Contact portions are in contact with each other in a case where the movable iron core displaces in a valve opening direction with respect to the valve body. A gap is formed between the contact portions in a valve closing state. In a state in which the movable iron core and the valve body move in different directions after the movable iron core collides with the fixed iron core while a valve is opened, a spring force is not applied between the movable iron core and the valve body.
