PROBLEM TO BE SOLVED: To constitute an injection nozzle which is suitable to apply to a standard type injection valve, and can prevent an improper injection from generating by a method wherein the base part of a rotatable cylindrical body having a discharging port, is inserted in the opening of the injection nozzle main body, and the discharging port is communicated or shut off by rotating the base part of the cylindrical body. SOLUTION: The base part of a rotatable cylindrical body 2 having a discharging port 3 of which the leading end part is bent into an L-shape to make it face a specified direction, is inserted in a horizontal opening 7 of an injection nozzle main body 1, and the upper tip opening 9 of a valve stem is inserted in the lower end opening of a vertical opening part 8 of the injection nozzle main body 1. Then, at an intermediate location of the horizontal opening 7 of the injection nozzle main body 1, an annular indent 5 is provided, and an annular protruding part 6 being provided on the outer peripheral surface of the rotatable cylindrical body 2 is fitted in the annular indent 5. By doing so, when the discharging port 3 is faced downward, an opening 10 being provided on the base part of the rotatable cylindrical body 2, communicates with the upper tip opening 9 of the valve stem, and when the discharging port 3 is faced upward, the communicating state between the opening 10 and the upper tip opening 9 can be shut off. |
