FUEL INJECTION VALVE AND MANUFACTURING METHOD FOR THE SAME

PROBLEM TO BE SOLVED: To obtain a fuel injection valve which enables improvement of water resistance with a simple structure, and to obtain a manufacturing method for the fuel injection valve.SOLUTION: In a fuel injection valve 1, a fuel injection hole is opened or closed by energization to an actuator. The fuel injection valve 1 includes: a body 100 provided with an opening 101 through which wiring 210 connected with the actuator passes; a mold material 110 covering the opening 101; a seal member 30 disposed at a position where an outer surface of the mold material 110 and an outer surface of the body 100 contact with each other; and a holding member 10 which applies pressure to a boundary surface between the mold material 110 and the body 100 to hold the seal member 30.SELECTED DRAWING: Figure 3 【課題】簡易な構成により耐水性を向上することができる燃料噴射弁及び燃料噴射弁の製造方法を得る。【解決手段】アクチュエータへの通電によって燃料噴射孔が開閉される燃料噴射弁１であって、アクチュエータに接続された配線２１０が通る開口１０１が形成された本体１００と、開口１０１を覆うモールド材１１０と、モールド材１１０の外表面と本体１００の外表面とが接触する位置に配置されたシール部材３０と、シール部材３０を、モールド材１１０と本体１００との界面へ向かって圧力を加えて保持する保持部材１０と、を備えたものである。【選択図】図３
