PROBLEM TO BE SOLVED: To provide a highly durable sprinkling nozzle which prevents foreign substances such as soil or sand from entering into a gap between an inner cylinder and an outer cylinder constituting the connection portion of a head and a body and in which the switching operation of the shape of discharged water is carried out smoothly. SOLUTION: The sprinkling nozzle 10 has a fitting structure comprising the inner cylinder 12a and the outer cylinder 13a in the connection portion between the head 12 and the body 13. The shape of the discharged water is switched by relatively moving the inner cylinder and the outer cylinder in and out while rotating them in the circumferential direction and by changing the relative positioning relation of the head 12 an the body 13. A ring member 30 comprising an elastic body is provided to the opening end of the outer cylinder 13a and a scraping wall 31a continuously formed in the circumferential direction of the inner cylinder 12a and capable of coming into sliding contact with the circumferential surface of the inner cylinder 12a is formed on the end surface of the ring member 30.
