PROBLEM TO BE SOLVED: To make a heat insulating member telescopic excellently following the extension-contraction of a tank member. SOLUTION: A fuel tank heat insulating structure 10 restrains heat transfer between a fuel tank 12 and an external part by a heat insulator 20 around the fuel tank 12. The heat insulator 20 is also reinforced by a bead 24. Here, since the bead 24 is divided in the longitudinal direction, the heat insulator 20 easily extends-contracts in the longitudinal direction of the bead 24. Since the bead 24 is also divided in a part where the heat insulator 20 is opposed to a recessed part 14 of the fuel tank 12, the heat insulator 20 easily extends-contracts in a part opposed to the recessed part 14. Thus, the heat insulator 20 easily follows the extension-contraction of the fuel tank 12 in a part opposed to the recessed part 14 in the longitudinal direction of the bead 24. The heat insulator 20 can extend-contract by excellently following the extension-contraction of the fuel tank 12. COPYRIGHT: (C)2004,JPO&NCIPI |
