Abstract: To provide a spout apparatus whereby expansion and deformation of the inner wall surface of the vortex generating portion such that a desired Karman vortex cannot be generated are prevented, even when the port portion is formed of an elastically deformable soft member. A spout apparatus for discharging hot or cold water with reciprocal motion, having a spout apparatus body and a vortex generating passage; whereby the oscillating element has a supply passage, a vortex generating passage, and a spout port passage, and the spout port passage is formed by an elastically deformable soft member, and is attached to the spout apparatus body so that a user can manipulate and deform the spout port passage, and the vortex generating passage is formed so as not to expand and deform even if internal pressure rises due to the supply of hot or cold water from the supply passage.

Abstract: To provide a spout apparatus which is easily maintainable by a user even when, in a fluid device utilizing Karman vortices, scale adheres to the Karman vortex generating portion. A spout apparatus for discharging hot or cold water while causing it to reciprocally oscillate, having a spout apparatus body and an oscillating element; whereby the oscillating element has a water supply passage, a vortex generating passage, and a spout port passage; the spout port passage is formed of an elastically deformable soft member and is attached to the spout apparatus body so that a user can manipulate the spout port passage to deform it; and the vortex generating passage is formed of an elastically deformable soft member, and is integrally formed with the spout port passage so that deformations of the spout port passage can be transmitted to this vortex generating passage.

Abstract: Provided is a shower apparatus which can stably supply bubbly water through all nozzle holes and can cause water droplets of large, uniform size to land continuously on the user so as to allow the user to enjoy a shower with a voluminous feel as if the user were being showered by large drops of rain. The shower apparatus includes a water supply unit, a throttle unit adapted to eject passing water downstream, an aeration unit adapted to produce bubbly water by aerating the water ejected through the throttle unit, and a nozzle unit provided with a plurality of nozzle holes used to discharge the bubbly water, wherein the throttle unit has a flat-shaped throttle channel and water ejected through the throttle channel plunges into an air-liquid interface as a sheet-like stream, thereby producing bubbly water, which is then discharged through the nozzle hole.
