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: There is provided a bathtub apparatus capable of satisfactorily detecting an electrocardiographic signal even in a state where water is being discharged into a bathtub by a water discharge device. The present invention is a bathtub apparatus (1) including a bathtub main body (2), a water discharge device (8) that discharges water toward inside of the bathtub main body and is provided above a first inner wall surface (2a) forming a short side of the bathtub main body, and electrodes (4a, 4b, 4c) attached to the bathtub main body to detect an electrocardiographic signal of a bathing person, where the electrodes are arranged on an inner wall surface of the bathtub main body, and are arranged closer to the first inner wall surface than a position (P) where water discharged from the water discharge device hits a water surface of the water stored in the bathtub main body.
