Abstract
A heat insulator apparatus for a vehicle floor, includes a plurality of heat insulating plates interposed between a vehicle floor and an exhaust part disposed below the vehicle floor in such a manner that the mutually adjoining heat insulating plates forms a gap therebetween to thereby form an air passage therebetween, for preventing the heat of the exhaust part from being transmitted to the vehicle floor. At least one of the heat insulating plates is formed such that an air entrance portion of the air passage is narrowed.
