PROBLEM TO BE SOLVED: To provide a fuel injection nozzle which can reduce a variation of injection amounts or injection speeds of fuel in a plurality of injection holes even if assembled obliquely, and can be easily designed in an optimum layout related to injection dispersion performance, and a fuel injection valve.SOLUTION: A sack chamber 100 in which fuel is accumulated is formed at a nozzle tip 18 by being surrounded by an inner wall 92 of a nozzle body 12 and an outer wall 94 of a needle valve 14. The sack chamber 100 includes a first space 102 located at a value head 90 side, and a second space 104 which makes the first space 102 communicate with the respective injection holes 22. The second space 104 extends along an inclined axis B which is inclined to a moving axis A, and the injection holes 22 are extended to angular directions (penetration directions D1, D2) having the same angles (injection angles φ) between the inclined axis B.SELECTED DRAWING: Figure 4 |
