发明名称 燃料噴射弁
摘要 A fuel injection valve includes a fixed core formed into a cylindrical shape, a valve plunger that can move closer to or away from the fixed core, a retainer formed with a substantially C-shaped cross-section having one long straight opening extending linearly along the entire length in an axial direction while having a tapered face on an outer periphery of each of opposite end parts in the axial direction and is press fitted into the fixed core, and a return spring provided between the retainer and the valve plunger. A cutout is provided in peripherally opposite end parts of the retainer for increasing the width between opposite end parts in a longitudinal direction of the opening. This enables the degree of freedom in selecting the material for forming a retainer while preventing the occurrence of galling or the generation of swarf when press fitting the retainer into the fixed core.
