PROBLEM TO BE SOLVED: To provide a jet nozzle and a vehicle body washing apparatus using the jet nozzle, with which energy loss of gas jetting is restricted and washing water is efficiently accelerated and caused to act on a surface to be washed.SOLUTION: A jet nozzle comprises: a blow nozzle 2 having an almost circular blow port 2a communicating with a blower device 4; and sprinkler nozzles 3 having sprinkler ports 3a communicating with a water supply pump 7. The sprinkler nozzles 3 are disposed on an upper part and a lower part in an outer periphery of the blow port of the blow nozzle 2, and washing water from the sprinkler ports 3a of the sprinkler nozzles 3 is made confluent with air blown from the blow port 2a of the blow nozzle 2 and is sprayed on a surface F to be washed.SELECTED DRAWING: Figure 4 |
