Abstract
A movable core includes a through-hole, which receives a main body of a needle therethrough, and a receiving recess, which is axially recessed in a stationary core side end surface of the movable core. The receiving recess is configured into an annular form and radially outwardly extends from the through-hole to receive a flange of the needle. A movable plate is placed on an axial side of the movable core, which is opposite from the nozzle. An axial length of the flange is smaller than an axial distance between a contact surface of the movable plate, which is contactable with the needle, and a bottom wall of the receiving recess in a contact state where the movable core and the movable plate contact with each other.
