  • the fastening member 69 can be screwed into the bottom wall portion 8a of the blower casing 8 through the motor flange 65b and the mounting plate portion 62f from below. Thereby, the assembly man-hour at the time of assembling the motor cover part 62 and the motor 65 to the ventilation casing 8 can be reduced.
  • an outside air introduction mode for introducing outside air into the upper air passage 17 and the lower air passage 18 by independently operating the first inside / outside air switching damper 4 and the second inside / outside air switching damper 5;
  • By setting the inside / outside air two-layer flow mode in winter, relatively dry outside air is supplied to the defrost outlet, and the windshield glass is well cleared, while relatively warm inside air is supplied to the heat outlet. Heating efficiency can be improved.
  • one of the upper layer blower fan 40 and the lower layer blower fan 50 such as the fan diameter and fan height of one blower fan Dimensional changes may be made.
  • the upper layer blowing fan 40 and the lower layer blowing fan 50 are separate bodies, even if the size of one blowing fan is changed, the other blowing fan is not affected. In addition, it is not necessary to newly install the other blower fan, and it is possible to cope with it at low cost.
  • the upper layer blowing fan 40 and the lower layer blowing fan 50 are separate bodies, a slide mold as in the case of integral molding becomes unnecessary, and the mold cost can be reduced. This effect is an effect when the upper layer blower fan 40 and the lower layer blower fan 50 are separately formed. However, when the upper layer blower fan 40 and the lower layer blower fan 50 are integrally formed, the number of parts is reduced. Can be achieved.
  • the motor cover 62 is provided on the lower bellmouth forming member 60 that forms the lower bellmouth mouth 61a communicating with the inside of the lower scroll portion 14 to cover the motor 65 from above. Therefore, it is difficult for water accumulated in the lower air passage 18 to enter the motor 65. Therefore, it is possible to prevent the motor 65 from malfunctioning.
  • the lower portion of the motor cover portion 62 of the lower bellmouth forming member 60 is fitted into the fitting hole 8 c of the bottom wall portion 8 a of the blower casing 8.
  • the lower bellmouth forming member 60 can be firmly fixed to the blower casing 8.
  • the sealing material S is disposed between the facing surface 62b provided at the lower part of the motor cover 62 and the inner peripheral surface of the fitting hole 8c of the blower casing 8, the water accumulated in the lower air passage 18 is removed. It is difficult to leak from between the lower part of the motor cover 62 and the fitting hole 8c, and the air in the lower air passage 18 is also difficult to leak from between the lower part of the motor cover 62 and the fitting hole 8c.
  • the vehicle air-conditioning blower according to the present invention can be used, for example, as a blower unit of a vehicle air-conditioner.
