An exterior heat exchanger 33 is provided with paths P1-P4. The flow rate of the air being blown by an exterior blower to pass through the path P4 closer to a refrigerant outlet of the exterior heat exchanger 33 is set to be higher than that of the air being blown by the exterior blower to pass through the path P1 closer to a refrigerant inlet of the exterior heat exchanger 33. An air-conditioning controller 22 activates cooling fans 37a and 38a during a defrosting mode of operation.

An exterior heat exchanger is provided with first to fourth paths. The flow rate of the air being blown by an exterior blower to pass through the first path closer to a refrigerant inlet of the exterior heat exchanger is set to be higher than that of the air being blown by the exterior blower to pass through the fourth path closer to a refrigerant outlet of the exterior heat exchanger.

A drainage member 20 disclosed herein includes a drainpipe 21 made of an elastic material and an engaging bevel 22 engaged with a circumferential edge of a through hole P1 of a floor panel P from outside a vehicle cabin. The drainpipe 21 includes, as its integral parts, front, rear, and lower engaging stops 23, 24, and 25 engaged with the circumferential edge of the through hole P1 from inside the vehicle cabin. The front, rear, and lower engaging stops 23, 24, and 25 are discontinuous with each other. The sum of the areas covered by the front, rear, and lower engaging stops 23, 24, and 25 is smaller than the area covered by the engaging bevel 22.

A drain hose 1 includes a drain hose body 10 and a hard member 20. The hard member 20 includes a notch 22 and hooks 21. The drain hose body 10 includes a protruding portion 14 provided to a part, of an outer periphery of the drain hose body 10, to which the hard member 20 is attached. The protruding portion 14 protrudes to be positioned in the notch 22, and, when force is applied to the drain hose body 10 in a direction to pull the drain hose body 10 from a through hole P1, depresses edge portions 22a of the notch 22 in a direction to expand the hard member 20 in diameter.
