PROBLEM TO BE SOLVED: To provide a liquid distribution mechanism for a lawn sprinkler that can retain a constant pressure for injecting high-pressure liquid and a constant injection rate with no change in the opening of a distribution valve for a long period of time and can optimize the injecting pressure and the injection rate of the high-pressure liquid according to the object of the work, the growing condition of the lawn and the difference in soil quality. SOLUTION: This liquid distribution mechanism is equipped with a rotary shaft 12 that is inserted into and supported with a block 1, a pusher-supporting member 13 that is detachably fitted from the top edge to one projection side of this rotary shaft 12, a pushing piece 10 that is supported by the supporting member 13 and moves around the periphery of the rotary shaft 12, an annular stepped face 15 of the outer periphery of the rotary shaft that decides the position to which the pusher-supporting member 13 is mounted, an adjusting sheet that is detachably intervened between the annular stepped face 15 and the pusher-supporting member 13 to change and adjust the pushing stroke by the pusher (pushing piece) and, a distribution valve 2 that distributes and feeds the high-pressure liquid when it is provided in a block so that it may be positioned on the periphery of the pushing piece and the head of the valve bar is pushed into by the pushing piece, and a driving mechanism that is connected to the other projection side to rotate the rotary shaft.
