PROBLEM TO BE SOLVED: To provide a sprinkler by which sprinkling can be performed by rotational force provided with a reduced flow rate. SOLUTION: Liquids jetted from jetting holes 30 and 40 corresponding to rotary grooves 56 and 66 successively strike against the groove wall faces 56A and 66A of the rotary grooves 56 and 66, so that a rotor 50 continues to rotate. Since rotational force is generated at the rotary grooves 56 and 66 provided on four places each in the upper and lower parts, i.e. on eight places in total, large rotational force is applied to a core part 94. Further, since the liquids jetted from the jetting holes 30 and 40 located at the positions other than the rotary grooves 56 and 66 strike against the sprinkling faces 52A, 54A, 62A, and 64A of sprinkling walls 52, 54, 62, and 64, and also, the rotor 50 is rotated, the sprinkling directions gradually change from the horizontal direction to the upper direction and lower direction in accordance with the inclination angles of the sprinkling faces 52A, 54A, 62A, and 64A. Since the sprinkling directions of the liquids jetted from the jetting holes 30 and 40 gradually continuously change to the upper direction and lower direction, the liquids can be diffused and sprinkled in all directions.
