1. An air conditioner that conditions air in a cabin for a vehicle, comprising:
a casing that forms an air passage through which air flows;
a blower fan arranged inside the casing to rotate about a fan axis to suck in air from one side in an axial direction and to blow out air in a direction away from the fan axis; and
a heating device arranged downstream of the blower fan in a flow of air inside the casing to heat air blown out from the blower fan, wherein
the casing includes a fan housing portion housing the blower fan and an equipment housing portion connected to the fan housing portion and housing the heating device,
the fan housing portion has a passage portion outside of the blower fan in a radial direction to form an outlet passage through which air blown from the blower fan flows,
the equipment housing portion has a warm air passage that allows air blown from the blower fan to flow to the heating device, and a bypass passage that allows air blown from the blower fan to bypass the heating device,
the warm air passage and the bypass passage are arranged in a first direction orthogonal to the axial direction,
a second direction is orthogonal to each of the axial direction and the first direction,
a blowout width dimension of the passage portion in the second direction is larger than that of the heating device in the second direction,
the blowout width dimension of the passage portion in the second direction is smaller than a blowout height dimension of the passage portion in the first direction,
the passage portion has an outer shape by a connection of a pair of short sides facing in the first direction and a pair of long sides facing in the second direction, and
the pair of long sides is formed in a straight line extended in the first direction.
