A new fuel injecting device is comprised of a nozzle body formed a fuel supply hole in the center top end for injecting the fuel to a combustion chamber, a plurality of the spiral grooves and the edge grooves formed vertically and alternately on the outer peripheral surface of the lower portion. Each edge groove is positioned between two adjacent spiral grooves for supplying the fuel through the fuel supply hole. Each spiral groove and edge groove are formed a flow sectional area reduced gradually from inlet to outlet. A cylindrical shaped nozzle case is openable upward or downward and adapted to accommodate the nozzle body at a lower portion and the injector at an upper portion. The injector is positioned on the nozzle body and the injection hole is tightly secured onto the fuel supply hole of the nozzle body.
