PROBLEM TO BE SOLVED: To provide a floor cooling structure which efficiently cools a floor high temperature part with a relatively simple structure.SOLUTION: A second catalyst 18 is disposed near feet of an occupant H in a space below a floor panel 30 thereby providing a floor high temperature part 32 in which a part of the floor panel 30 is heated to a high temperature. An insulator 36 having high air permeability than that of a floor mat 35 is provided in an area of the floor panel 30 which is located between the floor high temperature part 32 and the floor mat 35. Hot air of the floor high temperature part 32 is discharged through the insulator 36 by heat convection occurring in the insulator 36 and cooling air supplied from an air conditioner 23 penetrates into the insulator 36 to cool the floor high temperature part 32. |
