摘要:
A fuel injection valve according to the present invention has an expanded portion formed in a first injection-hole plate on an upstream side, thereby allowing positional misalignment between injection-hole portions. As a result, a radial dimension between an inner diameter-side circumferential edge of an upstream-side injection hole outlet portion and an inner diameter-side circumferential edge of a downstream-side injection hole inlet portion is not required. Thus, a plate thickness of a second injection-hole plate on a downstream side can be kept to minimum. As a result, weldability between an injection-hole plate body and a valve seat is improved.
