PROBLEM TO BE SOLVED: To provide a nozzle tip capable of being certainly detachably locked after being temporarily fixed to the tip of a mixing tip.SOLUTION: A nozzle tip is inserted into a discharge port Ma formed with a projecting stripe part Mab having a same inside diameter din the tip of a cylindrical part Maa having a same inside diameter don the tip side of a mixing tip M and is locked to the mixing tip M. An insertion part 1 into the discharge port Ma of the mixing tip M comprises: a temporary fixing cylindrical part 2 having a same outside diameter Das the inside diameter dof the projecting stripe part Mab of the mixing tip M; a taper part 3 provided with a level difference part 3a having an outside diameter Dwhich is reduced to a diameter of the inside diameter dor greater of the projecting stripe part Mab of the mixing tip M after a diameter increases to a diameter Dsmaller than the inside diameter dof the cylindrical part Maa of the mixing tip M toward the nozzle tip side continuously from the temporary fixing cylindrical part 2; and an engaging cylindrical part 4 having the same diameter Dcontinuously from the level difference part 3a of the taper part 3 and having a length longer than that of the projecting stripe part Mab of the mixing tip M. |
