PURPOSE: Provided is a rotational sprinkler which is automatically rotated within the scope of regular angle to scatter fertilizer or so on uniformly when a sower is moved so that it reduces labor cost for scattering remarkably. CONSTITUTION: The rotational sprinkler comprises the parts of: a sprinkler body(310) which is placed at the rear part of a base plate(8) in a vehicle frame(1); a scattering pipe(311) which is connected to a flexible pipe; a central axis which is fixed to be located at the center of an arc guide rail; a rotational lever for the scattering pipe which is combined with the central axis at one side and combined to ride over the arc guide rail and rotate at the other side; and a rotational drive tool for the sprinkler which rotates the rotational lever for the scattering pipe within the scope of regular angle.
