发明名称 FUEL INJECTION VALVE
摘要 PROBLEM TO BE SOLVED: To compress an elastic shock absorbing member before a stopper surface of a movable element abuts onto a confronting stopper surface in rising stroke of a valve needle, avoid generation of an impact peak by the deceleration, and minimize the generation of noise. SOLUTION: This fuel injection valve 1 of a fuel injection device for an internal combustion engine is provided with the valve needle 3 working with a valve seat surface 6 and forming a seal seat, and the movable element 20 fitted onto the valve needle. The movable element is provided with the movable element stopper surface 34 as a first stopper surface on an opposite side from the valve seat. The confronting stopper surface 35 is used as a second stopper surface working with the movable element stopper surface. The movable element stopper surface 34 and/or the confronting stopper surface 35 are provided with the elastic shock absorbing members 37 and 38 in a cutout 36. The shock absorbing member protrudes from the movable element stopper surface 34 and/or the confronting stopper surface 35.
