PROBLEM TO BE SOLVED: To provide a rotary sprinkler for setting the diffusion and sprinkling of a sprinkling liquid to an atomized state but not to a liquid drop state to diffuse and sprinkle the sprinkling liquid correspondingly to the kind and growing state of a plant, a sprinkling target region, a cultivation place or a weather condition. SOLUTION: At least a pair of upward jet orifices 6 and 6 and a pair of lateral jet orifices 7 and 7 are respectively arranged to the nozzle attached to a rotary head (b) in a truncated chevron shape. The mutual jet streams of the sprinkling liquid ejected from the pair of the upward jet orifices 6 and 6 and the mutual jet streams of the sprinkling liquid ejected from the pair of the lateral jet orifices 7 and 7 are respectively allowed to collide with each other in a forward region to be crushed and atomized and diffused while revolved as a whole.
