NOZZLE FOR SPRAYING MORTAR, AND COVERING MEMBER
PROBLEM TO BE SOLVED: To provide a nozzle for spraying mortar, the tip part of which is hardly clogged when the mortar is sprayed, and a covering member.SOLUTION: A nozzle for spraying mortar according to the present invention discharges the mortar. The tip of the nozzle is provided with a rubber nozzle part (tip part) that has a shape in which an inside diameter of the nozzle part becomes gradually smaller toward a mortar discharge opening. The nozzle has a metal covering member 20 for covering the nozzle part. The covering member 20 comprises a plurality of urging members 22 for urging the nozzle part inward.SELECTED DRAWING: Figure 2
【課題】モルタル吹き付け時にノズルの先端部分において詰まりにくいモルタル吹付用ノズル及びかぶせ部材を提供する。【解決手段】本発明に係るモルタル吹付用ノズルは、モルタルを吐出するモルタル吹付用ノズルであって、ノズル部分の内径は、モルタルの吐出口に向かうにつれて次第に小さくなる形状を有するゴム製のノズル部分（先端部分）を先端に備える。ノズル部分にかぶせる金属製のかぶせ部材２０を有し、かぶせ部材２０は、ノズル部分を内側方向へ付勢する複数の付勢部材２２で構成されている。【選択図】図２
