冷媒配管を作用荷重から保護する必要がある。By the way, it may be difficult to provide the refrigerant pipe opening on the vehicle floor immediately below the cooler unit because the body structure is relatively complicated. It is conceivable that the refrigerant pipe may be drawn out from the unit toward the front of the vehicle, and the refrigerant pipe may be penetrated downward by the floor panel of the vehicle entrance / exit with a relatively simple body structure. However, this floor portion is a place where the weight of the occupant often acts when getting on and off, and it is necessary to protect the rubber-coated refrigerant pipe from the acting load.
