the subject innovation is crops or relates to a sprinkler of the rotation force control unit used in the lawn, and more particularly, to the water a water pipe to be sprayed from the spray nozzle for a distance spraying the rotation axis is added to the rotor water is sprayed force in the spray nozzle for short-range spraying is to be by the water pipe to the axis of rotation offset a portion with added force to the rotor and happens, a change in pressure in the water supply while the spray nozzle for the local area sprayed by the spiral groove It changed so that the pressure of the water supplied to the water pipe to the spray angle to vary also the rotor is substantially maintain a constant number of revolutions relates to a rotation force control apparatus of the printers clutch. If a conventional map ppuryeoju not uniformly rotating sprinklers water the intermittent state, gat planted crops such jugido was a catastrophic failure of the crops grown on the muddy tunggyeo. The Utility Model Registration No. 20-0203265, the supply of water in case of drought. No. 20-0325181 is not smooth, so there was a lot of problems in a number of atomizing nozzle so the supply of water, at the same time to control the torque of the rotor this means you could be. The subject innovation is the upper end of the rotor 11 are engaged with teflon (12) closes the resistance value is so weak, and as a diameter of the rotor (11) is raised to a different packing for preventing water leakage minimal resistance. The rotor 11 is a spray nozzle for spraying distance along the water pipe (20,30) assembly (for example 2.4) and the assembly 63, a spray nozzle for spraying to near the other side (for example 2. 0) (73) to the spray nozzle (73 for controlling a rotating force, however, short-range applications of the rotor 11) assembly is a spray nozzle (73, by the spiral groove 56 and the circular key 55, the pressure of the water changes, ) changing the direction of, and control the rotational f
