Air conditioning device for vehicle

An air conditioning device for a vehicle, comprising:

• a blower unit in which a blower configured to generate an air flow toward a vehicle interior is housed;
• and
• a temperature adjustment unit in which a cooling heat exchanger configured to cool an air blown from the blower unit is housed, wherein
• the blower unit includes a first case member, the first case member having a first upper passage through which the air flow generated by the blower flows, a first lower passage through which the air flow generated by the blower flows below the first upper passage, and a first communication passage communicating with an air intake side of the blower below the first lower passage,
• the temperature adjustment unit includes a second case member, the second case member having a second upper passage communicating with the first upper passage, a second lower passage communicating with the first lower passage below the second upper passage, and a second communication passage located upstream of the cooling heat exchanger and in a lower area of the second lower passage and communicating with a condensed water discharge portion through which a condensed water of the cooling heat exchanger is discharged to the outside,
• the first case member and the second case member are joined with each other in a state where a portion forming the first communication passage and a portion forming the second communication passage face each other,
• the portion of the first communication passage facing the second communication passage includes a drain portion having a groove shape and configured to discharge the water which has entered the first communication passage, and
• the portion of the second communication passage facing the first communication passage includes a drain receiving portion having a groove shape, communicating with the first communication passage and configured to receive the water discharged from the drain portion.
