Air-conditioning unit for vehicle

An air-conditioning unit for a vehicle, comprising:

• an air-conditioning case in which an in-case passage is defined for air to be blown into a cabin;
• a blower having a blower fan arranged in the in-case passage to rotate around a fan axis so as to blow out air sucked from one side in an axial direction of the fan axis;
• and
• a rectifying mechanism arranged downstream of the blower fan in a flow of air in the in-case passage, a rectifying passage being defined in the rectifying mechanism to rectify a swirling flow generated by rotation of the blower fan relative to the air blown from the blower fan, wherein
• the rectifying mechanism includes a contracting rectifying passage having an inlet into which the swirling flow flows and an outlet through which the rectified air flows out, and
• a flow path area of the outlet is smaller than a flow path area of the inlet.
