In a vehicular air conditioning unit, an air conditioning case includes a space forming portion that forms a drainage space which is partitioned from an air passage. The space forming portion includes a drainage portion that discharges water from inside the air conditioning case to outside of the air conditioning case. Further, the space forming portion includes an upstream side communication portion that communicates the drainage space to an upstream side space on an air flow upstream side of the blower in the air passage. Further, the space forming portion includes a downstream side communication portion that communicates the drainage space to a downstream side space on the air flow downstream side of the blower in the air passage.
