PROBLEM TO BE SOLVED: To reduce the number of components.SOLUTION: A fuel tank A comprises: a tank body 10 constituting an accumulation space 11 for accumulating fuel F; and a heat accumulation layer 13 constituting the tank body 10 and containing a latent heat accumulation material 19. Temperature rise in the accumulation space 11 is suppressed since a phase of the latent heat accumulation material 19 of the heat accumulation layer 13 changes to take heat in the surroundings of the tank body 10 when temperature in the surroundings of the tank body 10 becomes high. The fuel tank A requires only a few components in comparison with the case of providing separate components from the tank body 10 since the tank body 10 has the heat accumulation layer 13. In addition, the heat accumulation layer 13 exerts a high heat insulation function since it includes the latent heat accumulation material 19 with heat capacity larger than that of a material whose phase does not change.SELECTED DRAWING: Figure 2 |
