PURPOSE:To simplify a work of connecting a needle valve to a movable core of an injection valve, by engageably setting one end of the needle valve into a support hole provided on an axial line of the movable core and tightly inserting a fixing pin into a transverse hole penetrably extended through the needle valve and the movable core. CONSTITUTION:A solenoid type fuel injection valve comprises a movable core 12 arranged at a face-to-face position to the bottom end of a pipe-shaped core not shown in the drawing. To a lower portion of the movable core 12, a needle valve 14, which is seated to and lifted from the valve seat of a nozzle body not shown in the drawing, is integrally mounted. Here in the lower portion of the movable core 12, a bottommed support hole 12c is formed on its axial line, and into said support hole 12c and a top end part 14a of the needle valve 14 is engageably inserted. While a transverse hole 24 is drilled to allow it to be extended through the movable core 12 and the top end of the needle valve 14. The tight insertion of a fixing pin 23 into said transverse hole 24 can firmly perform the work of connection between the both core 12 and valve 14. |
