Abstract
An upper end 3 of a nozzle tip 2 is adapted to have an inside diameter dimension smaller than an outside diameter of a lower portion of a barrel 4, so that nozzle tips 2 are not piled up. An upper curved surface 11, which is curved in an outer direction of the nozzle tip 2 starting with a boundary portion between the barrel 4 and a leading end opening 5 of the nozzle tip 2 and the leading end opening 5, is formed. A lower curved surface 12 is formed continuously from the upper curved surface 11 to be curved in an inner direction. An angle formed between a line tangent to a boundary portion 13 between the upper curved surface 11 and the lower curved surface 12 and a center axis of the nozzle tip 2 is adapted to fall within a range between 45° and 20°.
