<p>In order to ensure that operation does not become unstable even when a wax component included in fuel solidifies, in a fuel injection valve (1) comprising a nozzle (3) fixed to a leading end portion of a nozzle holder (2), with the nozzle (3) being configured such that a nozzle needle (32) inserted into a guide hole (33) inside a nozzle body (31) is guided by the guide hole (33) and moves in an axial direction to open/close an injection hole (35), a tapered portion (33B) that widens toward the nozzle holder (2) is disposed in the guide hole (33) . Thus, when the component included in the fuel solidifies, the solidified matter can be speedily discharged from a gap (G) serving as a fuel leak passage formed between the nozzle needle (32) and the guide hole (33).</p> |
