Abstract

　可動コアおよび弁体が同軸に連なって成る弁組立体が、固定コア側への近接端が規制されつつ弁座への着座側にばね付勢される電磁式燃料噴射弁の製造にあたり、固定コア（２２）の前端から磁性円筒体（９）の前端までの第１距離（Ｌ１）を測定し、弁座部材（１０）および弁組立体（１７）を同軸に保持した状態で可動コア（１８）の後端から所定量突出したストッパ（２８）の後端から弁座部材（１０）の環状肩部（１０ｃ）までの第２距離（Ｌ２）が第１距離（Ｌ１）から所望の値だけ小さくなるようにストッパ（２８）および可動コア（１８）を形成し、磁性円筒体（９）の前端に環状肩部（１０ｃ）が当接するまで圧入筒部（１０ａ）を磁性円筒体（９）の前部に圧入した状態で磁性円筒体（９）および弁座部材（１０）を突き当て溶接する。これによりコスト低減を図りつつ弁体のストローク調整を容易とし、同軸精度を高めて弁座部材および磁性円筒体を結合することができる。
