ABSTRACT:
In an automobile having an exhaust gas purifying device such as a catalytic converter beneath the floor of the vehicle body, a heat absorption layer is provided, within a space bounded on its lower and upper sides by the purifying device and an interior covering for the floor to prevent the covering from being burned in case of an abnormal rise in the temperature of the purifying device. The essential material of the heat absorption layer is a hydrate which loses its water of hydration at a temperature to which is heated the heat absorption layer in case of the abnormality.
