部材９で覆ったものである。As countermeasures against this problem, there are methods such as arranging fuel pipes to avoid heating parts to prevent the fuel from heating, and methods of using a fuel cooling device that actively cools the fuel. As a cooling device for this fuel, the one shown in FIG. 3 has been proposed (Japanese Unexamined Patent Publication No. 128653/1983). This consists of a compressor 2 that is driven by an engine 1 via a belt and compresses refrigerant, a condenser 4 that cools the compressed refrigerant with 7 am 3 and liquefies it, and a liquid tank that stores the liquefied refrigerant. 5 and an evaporator I that vaporizes the refrigerant that has passed through the expansion cell 6 and cools the air inside the vehicle.
A part of the fuel pipe connecting the fuel tank 8 and the engine 1 is brought into contact with a part of the pipe connecting the fuel tank 8 and the engine 1, and this contact part is covered with a heat insulating member 9.
