[Prior Art]

 Conventionally, as this type, a pressure regulating lid is provided on the upper part of the nozzle cylinder attached to the rising pipe via a screw rod, and the pressure regulating lid is slightly raised so that a gap is formed between the upper end of the nozzle cylinder and the pressure regulating lid. The water that has been formed and has passed through the nozzle cylinder is sprayed, and when the pressure control lid is lowered and the pressure control lid is brought into contact with the upper end of the nozzle cylinder, the above-mentioned gap is eliminated and a water spray nozzle capable of stopping water is provided. It is proposed in Japanese Patent Publication No. However, in the water spray nozzle that sprays water using the gap between the pressure control lid and the upper end of the nozzle tube, water is stopped by the contact surface between the lower surface of the pressure control lid and the upper end of the nozzle tube. However, there is a problem in that water cannot leak and water cannot be completely stopped if the two with a large area are not satisfactorily rubbed together.

As a solution to this problem, in Japanese Utility Model Laid-Open No. 57-115666, a water passage is vertically provided in a nozzle body, and the water passage is rotatably horizontally provided so as to cross the water passage. There has been proposed a water sprinkling nozzle having a water sprinkling hole formed at a crossing portion and provided with a water sprinkling amount adjusting bolt having one side provided outside the nozzle body.

[0004]

[Problems to be solved by the device]

 In the water sprinkling nozzle equipped with the water sprinkling amount adjusting bolt, water can be stopped by turning the water sprinkling amount adjusting bolt so that the water passage hole is not connected. By the way, in the sprinkling nozzle, the water that has passed through the relatively small-diameter water passage flows into a water sprinkling chamber that is larger than the water passage hole to regulate the water, and then is sprinkled from a plurality of water spouts connected to this water sprinkling chamber. However, when water flows from a wide sprinkling chamber to a narrow spout, loss of water flow easily occurs, and the sprinkling amount tends to be uneven depending on the direction of sprinkling holes. When used in a water spray nozzle that sprays water, it was difficult to spray water evenly on the side surface of 360 °.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sprinkling nozzle capable of improving water stopping property and capable of uniformly sprinkling water on a side surface of 360 °.
