摘要： Apparatus for spouting powder or fluid and including means for preventing operational problems caused by static electricity without requiring grounding devices is formed with a spout tube embodying therein a nozzle and defining a flow passage through which the powder or fluid flows. A transport tube through which the powder or fluid moves to the spout tube is provided and a main body is arranged to contain the powder or fluid from which it is delivered to the transport tube. The invention particularly includes a projecting electricity-eliminating member composed of material having volume resistivity of 10.sup.8 .OMEGA.-cm or less. The electricity-eliminating member is placed in the flow passage facing the flow layer of the powder or fluid flowing through the device and is electrostatically connected to the main body. The electricity-eliminating member is shaped in a particular configuration for eliminating static electricity developed during operation of the equipment without requiring grounding of the device.
