Claims

[Scope of utility model registration request]

A fuel injection nozzle whose tip is inserted into a hole drilled in a cylinder head, and facing notches are carved in the peripheral wall of the exposed end, and a predetermined interval formed by press-forming sheet metal. A bridge having a U-shaped cross section consisting of a pair of rising parts that stand apart in parallel and a bridge part that connects the lower ends of these parts to each other, a piece that is placed on the upper surface of the central part of the pair of rising parts of the bridge, and A bolt hole drilled in the center of the piece and a bolt hole drilled in the center of the bridge section are passed through in this order, and the tip thread part is screwed into the screw hole drilled in the cylinder head. A bolt is provided, a slit extending longitudinally from the center of the front edge of the bridging portion of the bridge into which the notch fits, and a downwardly convex cylindrical surface that abuts the bottom surface of the notch on the lower surface of the front end. and a downwardly convex cylindrical surface abutting the upper surface of the cylinder head on the lower surface of the rear end, and a cylindrical surface formed on the lower surface of the bridge on the upper surface of the central part of the pair of rising parts of the bridge. A fuel injection nozzle fixing mechanism characterized by forming an upwardly convex cylindrical surface that aligns with the surface.
