PROBLEM TO BE SOLVED: To provide a vehicle that can be built in a latent heat and heat storage material in a car body without entailing any increase in cost and to make a space, where this material is built in, so as not to be limited at all. SOLUTION: At least on a ceiling 2 of a car body, a latent heat and heat storage material 5 using alkyl hydrocarbon, an ethylene propylene copolymer as the chief ingredients is installed in space between an outline 3 and an interior material 4. Viscosity in the alkyl hydrocarbon liquefied at the time of heat storage is increased in quantity with the ethylene propylene copolymer, while the liquefied alkyl hydrocarbon, the ethylene propylene copolymer are held by the polyethylene or a skeletal material, whereby automorphic properties in the latent heat and heat storage material 5 is thus improvable. |
