Abstract
A liquefied gas dispensing nozzle having a cylinder with its axis in a vertical direction, and a plug to be inserted into the cylinder from above as its main elements. A plurality of slit portions for letting through the liquefied gas are formed in parallel in an axial direction of the cylinder from the upper end to the lower end in an inner circumferential face of the cylinder contacting to an outer circumferential face of the plug. A width of at least one or more pair of mutually opposed slit portions is generally constant from its upper end to lower end and its slit bottom is inclined so that the depth of the slit becomes gradually shallower from upper end to lower end. Each slit portion of the cylinder is closed with the plug when the plug, which is movable vertically relative to the cylinder, reaches the lowest end position. A rounded portion formed by rounding a corner portion of the lower end of the slit portion includes an inclined slit bottom.
