A clean out rod that passes through the inside so as to be movable forward and backward along the axis is biased with spring elasticity to give the tail end on which the plunger is crowned a constant outward protrusion, In a spray nozzle device in which a needle at the tip passes through and freely faces the inner end of a chemical liquid nozzle opening, an intermediate plate whose lower part is swingably supported is biased by spring elasticity so that the outer end of the plunger is always attached to the upper end. A chemical liquid nozzle opening clogging drive device comprising an eccentric cam that is fixed to the outer end of a motor shaft and can freely press the plunger via the intermediate upper end portion every rotation. 2. The clean out rod, which runs through the inside so that it can move forward and backward along the axis, is biased with spring elasticity to give the tail end, which is crowned with the plunger, a constant outward protrusion, and the tip needle is placed close to the inner end of the chemical liquid nozzle mouth. A chemical liquid nozzle opening clogging drive device, in which a pusher flange plate fixed to an outer end of a piston rod of a cylinder/piston mechanism is arranged to face the outer end of the plunger, in a spray nozzle device which can be freely faced through the plunger.
