In a vehicular air conditioner having an insertion hole for inserting an air filter adjacently on the upstream side of an evaporator, the air filter is inserted and mounted along guide rails provided on the upper and lower inside walls of a cooler case, and a drain pan and a drain port are formed at the cooler case bottom surface portion corresponding to the installation position of the evaporator, a drain groove extends from the lower cooler case bottom surface portion on the upstream side of the lower guide rail to the drain pan to prevent the rainwater, sucked together with the air and blocked by the lower guide rail, from leaking into the cabin and to discharge the rainwater to the outside of the vehicle.
