It is made by fixing a net that is also flexible, and can be folded by both flexibility (and magnetism). Further, the frame member and the net are configured so that at least a part of the region is made of resin and the folding can be maintained by magnetism as a whole. However, although this type of vehicle screen door can secure a minimum ventilation function, it cannot actively air-condition, so it is difficult to secure a substantial air-conditioning function on a tropical night on a hot summer day.

On the other hand, a vehicle air conditioning system in which a second in-vehicle air conditioner is mounted by retrofitting is also known from Patent Document 2. This vehicle air conditioning system is installed inside the cabin of the cab and cools the air in the cabin by heat exchange with the refrigerant, and is installed outside the cabin and exchanges heat with the outside air to exchange the heat with the indoor unit. It is equipped with an outdoor unit that releases heat from the refrigerant that has absorbed heat in the unit, and the indoor unit has an evaporator that exchanges heat between the refrigerant whose temperature has been lowered by evaporation and the air inside the vehicle, and below the evaporator. It has a drain pipe for draining water from the evaporator to the outside of the passenger compartment, a bottom to which one end of the drain pipe is connected, and a side portion erected so as to surround the bottom from the side edge of the bottom. It has a drain container, and the bottom of the drain container is inclined downward toward the connection with the drain pipe, and the inclination angle is set to be larger than the reference inclination angle assumed when the vehicle is parked. It is provided.
