The case includes: a drain port provided on a bottom portion of a downstream-side air passage in the filter arrangement area; an insertion port provided on a side surface of the case and configured to allow insertion of the filter into the filter arrangement area; a water receiving portion provided on a bottom portion of an upstream air passage in the filter arrangement area; a drain channel passing below the filter arrangement area and configured to introduce water from the water receiving portion to the drain port; and a waterproof wall that covers a lower corner portion on the insertion port side of an upstream-side boundary of the filter arrangement areas. The waterproof wall is increased in height toward the insertion port.
