PROBLEM TO BE SOLVED: To provide a washing device automatically self-washing a jet nozzle by running washing water of a given pressure by a given flow rate for a given time, simultaneously with the operation stop. SOLUTION: This washing device is provided with the jet nozzle 4 in which a jetting port is throttled by a set pressure of washing water (washing fluid) supplied from a washing water supply pipe (fluid supply line) 2, jetting the washing fluid, and which self-washes the jetting port with washing water by enlarging the port when the pressure of the washing fluid is lowered below the set pressure. The device is also provided with an accumulator 14 storing part of the washing water flowing in the washing water supply pipe 2 when operating the washing device, and an opening/closing valve (pressure reducing means) V3 reducing the pressure of the washing water stored in the accumulator 14 and running it to the jetting nozzle 4 when the operation of the washing device is stopped, for self-washing the jetting nozzle 4.
