  • the air direction changing member and the actuating member can change the direction of the conditioned air blown from the air outlet according to the temperature of the air conditioned air blown from the air outlet. Therefore, when cold air is blown out from the air outlet, the operating member is extended to blow the cold air toward the occupant's upper body, and when hot air is blown out from the air outlet, the operating member is shrunk toward the occupant's lower body. It is possible to change the direction of the conditioned air so as to blow out the warm air. Therefore, this seat air conditioner is described in the first embodiment without separately providing a blowout port for blowing out hot air and a blowout port for blowing out cold air as in the second and third embodiments. As described above, the comfort of passengers can be increased efficiently with a small number of outlets.
