Arrangement structure for protecting a drain hose of a vehicular air conditioning case

Abstract

In a arrangement structure of a drain hose that drains water from an air conditioning case to an outside of a vehicle, the drain hose is disposed to extend along a silencer provided in the inside of the vehicle. The silencer is formed with a depression and the drain hose is arranged in the depression. Thus, loads such as by passenger's feet and baggage are received by the silencer, thereby reducing crush of the drain hose. The drain hose can be made of rubber and is flexibly shaped along its arrangement route. Accordingly, the drain hose does not need separate flexible joint members at positions corresponding to bends in the arrangement route. Since the drain hose is supported in the depression, fixing members for fixing the drain hose are not required.
