  A gas component is supplied into the face duct 31c. According to this, since the gas component supplied in the face duct 31c is reliably blown out from the face blowout port 31d, it can be delivered to the occupant's nostril more reliably.

  Further, the gas component supply means 43 is assumed to be the ion generator 43A. According to this, generally, when negative ions in the air are increased, the negative ions enter the lungs and are absorbed by the human body, reducing the active oxygen in the blood and affecting the autonomic nerve to stabilize the emotion. it can.

  Further, the gas component supply means 43 is assumed to be an air purifier 43A. According to this, the stress applied to the occupant is blown out by blowing out air that has purified gaseous pollutants contained in the air, such as various odors and exhaust gases that are generated in the passenger compartment of the vehicle or flowing from outside air. Can be reduced and comfortable.
