Abstract

PURPOSE:To charge spouting and outflow state by tightly fitting an intermediate cylinder on the outside of a nozzle main body with a closing member between, and by opening and closing a through-hole provided to the outer peripheral wall of main body and moreover by communicating said hole to a sprinkling port of a different type provided to an outer cylinder. CONSTITUTION:The intermediate cylinder 16 surrounding the nozzle main body 6 forms an inner flow passage by keeping a specific clearance on the outer periphery of said main body 6, and the closing member 23 is provided to the inner peripheral wall positioned in the middle part of the intermediate cylinder 16. And, by sliding the intermediate cylinder 16, the through hole 5 provided to the outer peripheral wall of main body 6 is able to be positioned before and behind the closing member 23. An outer cylinder 9 surrounds the outer periphery of the intermediate cylinder 16 and forms an outerflow passage 17 of a specified clearance, and the end part of said flow passage 17 is communicated to the through-hole 5 when the closing member is moved backward, and the top part of a different type. Thus, by sliding the intermediate cylinder, the outflow state of water is changed to a straight state or to a sprinkling state.
