[Schematic Configuration of Cross-Flow Fan Device According to First Embodiment]
With reference to FIGS. 1-3, the structure etc. of the crossflow fan apparatus 1A which concern on 1st Embodiment are demonstrated.

  First, as shown in FIG. 1, a cross flow fan device 1A according to the present embodiment is covered with a casing 200 formed of resin or the like, and is disposed on a ceiling 300 in a vehicle interior of a vehicle V. It is a device that serves as a circulator that circulates conditioned air to assist air conditioning.

  By this cross flow fan device 1A, the conditioned air blown from the air conditioner installed on the driver's seat side and flowing into the ceiling is sucked from the suction port 10a (10b) opened to the front side and opened to the rear side. By blowing out toward the rear seat from the air outlet 15a (15b), it plays a role of assisting the air-conditioned air to circulate efficiently through the entire vehicle interior including the rear seat.
