Definitions

  • the thickness of the ring portion 61 becomes thinner from the inner peripheral side to the outer peripheral side. That is, the inner thickness t1 is larger than the outer thickness t2. Therefore, the fluid loss of air in the auxiliary ring 60 can be reduced, and the air blowing characteristics can be improved.
  • the thickness of the auxiliary ring 60 decreases from the connecting portion 62 to the ring portion 61 as it goes to the outer peripheral side. Also in this case, the air blowing characteristics can be further improved. Further, since the auxiliary ring 60 is thinner on the inner peripheral side than on the outer peripheral side, the fan block 30 of the cross flow fan 10 can be easily removed from the mold during injection molding.
