Abstract: A centrifugal blower includes a centrifugal fan and a separation cylinder. The centrifugal fan has a separation plate. The separation cylinder is disposed inward of the blades in the radial direction of the centrifugal fan. The separation plate has an inner end surface extending from the one side to the other side in the axial direction at a position of an inner end in the radial direction. The separation cylinder has a separation cylinder end surface extending from the one side to the other side in the axial direction at a position of an end on the other side in the axial direction. A height of one of the separation cylinder end surface and the inner end surface in the axial direction is larger than a height of the other of the separation cylinder end surface and the inner end surface in the axial direction.

Abstract: An air conditioning device has an electric blower, an air conditioning case, a cooling heat exchanger, and a partition wall. The electric blower has an electric motor, a fan, and a blowing case. Air from the blowing case flows toward the vehicle interior through the air conditioning case. The cooling heat exchanger is disposed in the air conditioning case. The partition wall is disposed on an upstream side of the cooling heat exchanger in the air conditioning case and partitions an inside of the air conditioning case into a first ventilation path and a second ventilation path. The blowing case is connected to a portion of the air conditioning case located on the upstream side of the cooling heat exchanger. The portion of the air conditioning case supports the partition wall formed along a flow direction of a main flow of the air blowing from the blowing case.
