摘要： The invention relates to a press-machined fuel induction pipe (40), a hollow tubular type of fixed core (1) with a flange at its upper end, and a nozzle holder (18) that was press-machined into a slender tubular shape and has an orifice plate (19) equipped with a valve seat (19a) at the lower end of the nozzle holder (18), are connected by welding. The upper inner surface of nozzle holder (18) and the outer surface of fixed core (1) are welded after being press-fit. A movable core (14) and a valve body (16) are connected to the welded assembly via a point (15) having a spring function. On the outer surface of nozzle holder (18) is provided an electromagnetic coil (2), the outside of which is provided with a tubular yoke (4) whose upper end is connected by welding to the flange (1a) of fixed core (1) and whose lower end is press-fit on the outer surface of nozzle holder (18).
