Abstract: Disclosed is a blowing unit of an air conditioner for a vehicle, having a two-layer structure and capable of effectively suppressing a flow of air flowing backward around a scroll bell mouth. In a blowing unit of an air conditioner for a vehicle, having a scroll case in which a first flow path and a second flow path are partitioned so as to separate inside and outdoor air to be sucked, the scroll case has a partition wall for separating a suction part of the first flow path and a suction part of the second flow path, and the partition wall has an air backflow prevention part for preventing air flowing into one of the first flow path or the second flow path from flowing backward into the other.
