（１０）、 （１０′）から噴出されることとなる。In the device of the present invention having the above configuration, the impeller (4) at the inner bottom of the water chamber (1) is rotated by water vigorously jetted from the tip opening (2) of the water conduit (3). By rotating the central gear (5) that is integrated with the impeller (4), the planetary gear (8) meshed with it is rotated, and the planetary gear (8) rotates on its own axis and inside the water chamber (1). Since it revolves along the internal gear (6) formed on the peripheral wall, the hollow planetary gear shaft (7) integrated with it and the nozzle head (9) at its tip rotate and revolve, and the water chamber ( 1
) flows in from the lower end opening of the hollow planetary gear shaft (7) due to water pressure, and is ejected from the nozzle holes (10), (10') of the nozzle head (9).
そこで上記水室（１）の中心垂直線に対し中空遊星歯車
軸（７）の傾き角度をαとし、同中空遊星歯車軸（７）
と直交するノズルヘッド（９）面に対しノズル孔（１０
）の仰角をβとすると、上記ノズルヘッド（９）が自転
すれば、上記ノズル孔（１０）の水室（１）の設置面に
対する仰角は（β−α）から（α＋β）となり、更に（
β−α）となる変化を繰り返すこととなる。Therefore, the inclination angle of the hollow planetary gear shaft (7) with respect to the center vertical line of the water chamber (1) is set to α, and the hollow planetary gear shaft (7)
The nozzle hole (10
) is the elevation angle of β. If the nozzle head (9) rotates, the elevation angle of the nozzle hole (10) with respect to the installation surface of the water chamber (1) changes from (β-α) to (α+β), and furthermore, (
β−α) will be repeated.
従って第４図に示す様にα＋β＝９０°を図中Ｃとすれ
ば上記ノズル孔（１０）は上記水室（１）の真上、即ち
垂直線上を向くことになる。つまり角度βを最大飛水距

によって、上記ノズル孔（１０）、 （１０′）の向き
は自在に変化する。Therefore, as shown in FIG. 4, if α+β=90° is designated as C in the figure, the nozzle hole (10) will face directly above the water chamber (1), that is, on a vertical line. In other words, if the angle β is determined so as to give the maximum distance of water spray, the area where water can be sprayed will be maximized. Furthermore, the directions of the nozzle holes (10) and (10') can be freely changed by combining the revolution angle and the autorotation angle of the nozzle head (9).
次に内歯車（６）と歯数Ｚと遊星歯車（８）の歯数Ｚと
の比を整数倍とするとノズルヘッド（９）の回転により
、ノズル孔（１０）の描く軌跡は１公転後も同じである
が、整数倍よりも僅かに大きいか、又は小さければ２公
転目から描く軌跡は１公転時の軌跡より僅かにずれるこ
とになり、図中ｄで示す様にノズルヘッド（９）の１回
転後の１公転不足分が生じる事となる。従ってノズルヘ
ッド（９）の自転及び公転を継続すれば散水可能円形領
域ｅ内に於いて（まな（散水することとなる。Next, if the ratio of the number of teeth Z of the internal gear (6) and the number of teeth Z of the planetary gear (8) is an integral multiple, the trajectory drawn by the nozzle hole (10) will change after one revolution due to the rotation of the nozzle head (9). is the same, but if it is slightly larger or smaller than an integer multiple, the trajectory drawn from the second revolution will deviate slightly from the trajectory from the first revolution, and as shown by d in the figure, the nozzle head (9) There will be a shortfall of one revolution after one revolution. Therefore, if the nozzle head (9) continues to rotate and revolve, water will be sprayed in the circular area e where water can be sprayed.
そこでα十β＝９０°、内歯車（６）と遊星歯車（８）
の歯車数比をｎ：２ｎ＋θとすれば、ノズルヘッド（９
）は１回の自転の間に（３６０−３６０θ／２ｎ十θ）
″、即ち１回転より（３６０θ／２ｎ十θ）°少ない回
転を行う。Therefore, α + β = 90°, internal gear (6) and planetary gear (8)
If the ratio of the number of gears is n:2n+θ, then the nozzle head (9
) during one rotation (360-360θ/2n+θ)
'', that is, the rotation is (360θ/2n+θ)° less than one rotation.
従って上記ノズルヘッド（９）の１回の自転中に上記ノ
ズル孔（１０）の仰角は、（β−α）°から真上を向き
、又（β−α）°になる変化を二度繰り返す。Therefore, during one rotation of the nozzle head (9), the elevation angle of the nozzle hole (10) changes twice from (β-α)° to directly upward, and then to (β-α)° twice. .
つまりノズル孔（１０）から噴出する水の落下点の軌跡
ｆは第５図に示す如くなり、これを連続的に繰返すこと
によって第６図に示す様に、円形領域ｅ内にくまなく散
水可能となる。In other words, the trajectory f of the falling point of the water ejected from the nozzle hole (10) is as shown in Figure 5, and by continuously repeating this, water can be sprayed all over the circular area e as shown in Figure 6. becomes.
なお図中に示す様に上記ノズルヘッド（９）上に複数個

更にくまなく散水可能となる。In addition, when multiple nozzle holes (10), (10') are opened on the nozzle head (9) as shown in the figure,
Furthermore, it becomes possible to sprinkle water evenly.
