Fuel Injection Valve

A fuel injection valve comprising:

• a valve body openable and closable to jet fuel and block the jet of fuel;
• a nozzle body having a valve seat surface capable of coming into contact with the valve body to block the jet of fuel;
• and
• an orifice plate disposed downstream of the valve seat surface with respect to the flow of fuel and having
• a swirling passage adapted to allow fuel to pass therethrough,
• a swirl chamber disposed downstream of the swirling passage, and
• a plurality of fuel injection holes adapted to jet swirl fuel;
• wherein the nozzle body has an end face portion with a downwardly convex inclined surface, the inclined surface being formed stepwise, and the orifice plate having the swirling passage and the swirl chamber is fixedly inserted into the nozzle body by being guided by a concave groove-outer circumferential wall portion provided in an outer circumferential portion of the nozzle body.
