FLOOR HEAT INSULATOR

PROBLEM TO BE SOLVED: To provide a simple floor insulator capable of reducing an atmospheric temperature at the front part of a vehicle before a dash panel by introducing air to the front of the vehicle after a stop of an internal combustion engine.SOLUTION: A floor heat insulator 12 has a component disposed on the front side of a dash panel partitioning an engine room at the front of a vehicle including an internal combustion engine and a car room from each other, is disposed between a vehicle floor connected to the dash panel and an exhaust pipe disposed below the vehicle floor and connected to the internal combustion engine, and one end 12a thereof is communicated with the front of the vehicle. In the floor heat insulator 12, a projection part 13 projecting upward in the vehicle is formed in a longitudinal direction. When high-temperature air flows into the engine room, the high-temperature air is prevented from rising along the dash panel to stay before the dash panel, and an atmospheric temperature is reduced.
