Abstract
The present invention is a spout apparatus () for discharging water, including a spouting apparatus main body () and an oscillation inducing element () for discharging water with reciprocating motion; wherein the oscillation inducing element has: a water supply passageway (); a water colliding portion () for generating vortexes of mutually opposing circulations at the downstream side thereof by the collision of hot or cold water; a vortex street passageway () having a tapered part, placed on the downstream side of the water supply passageway, which narrows in flow path cross section toward the downstream side; a separating portion () for suppressing the Coanda effect acting on the flow of water along the wall surface of a vortex street passageway; and a flow-aligning passageway () having an essentially fixed flow path cross section which aligns the flow of hot or cold water which has passed through the separating portion.
