SOLUTION: A nozzle body 3 is formed with a conical nozzle body side seat surface 33a and a nozzle valve 5 is slidably stored in the nozzle body 3. The nozzle valve 5 is provided with a cone part 54 and the tip of the cone part 54 is formed of a flat surface 54a orthogonally crossing with a nozzle valve central axis C. The boundary between the cone part 54 and the flat surface 54a is made to contact with the nozzle body side seat surface 33a. COPYRIGHT: (C)2004,JPO&NCIPI
