Abstract
A magnetic type fuel injection valve comprises a stationary core magnetized upon energization of a magnetic coil, and a movable core juxtaposed at one end to the stationary core to be normally urged away therefrom by a spring and formed at the other end with an axial bore for receiving one end of a needle valve normally closing a fuel injection nozzle. The movable core is movable as being attracted toward the stationary core together with the needle valve upon magnetization of the stationary core to thereby open the fuel injection nozzle. Through the wall portion of the movable core surrounding the axial bore is formed a transverse hole extending perpendicularly to the axial bore, and another transverse hole is formed through the one end of the needle valve in a manner to align with the first-mentioned transverse hole. A securing pin is snugly fitted in the transverse holes to securely connect the needle valve to the movable core.
