| description | PROBLEM TO BE SOLVED: To reduce a risk of degradation of durability caused by occurrence of cracking.SOLUTION: A fuel injection valve includes a valve closing body kept into contact with a seat member to seal a fuel, and a rod constituted integrally with the valve closing body through a welding portion. An outer peripheral portion of the rod has the cylindrical shape, and includes a diameter reduction portion having an outer diameter reduced toward a tip of the rod. The valve closing body and the diameter reduction portion of the rod are welded into the recessed shape, and the welding portion has the shape to smoothly connect the valve closing body and the rod.SELECTED DRAWING: Figure 3
【課題】そこで、本発明はクラックなどが発生して耐久性が低下する虞を抑制することを目的とする。【解決手段】本発明の燃料噴射弁は、シート部材と接触して燃料をシールする弁閉鎖体と、前記弁閉鎖体と溶接部を介して一体に構成されるロッドを備え、前記ロッドの外周部は円筒形状から形成されており、ロッド先端にかけ外径が縮小していく縮径部を備えており、前記弁閉鎖体と前記ロッドの縮径部が凹み形状に溶接され、溶接部の形状が前記弁閉鎖体と前記ロッドとを滑らかに結ぶ形状であることを特徴とする。【選択図】 図３ |
