PROBLEM TO BE SOLVED: To provide a heat insulation structure of rubber vibration isolator in an engine mounting part, which effectively performs heat insulation even when having a large amount of heat generation and protects the rubber vibration isolator by arranging two heat insulating boards between an exhaust manifold and the rubber vibration isolator and forming ventilating space between the heat insulating boards. SOLUTION: In the engine mounting part where vibration of an engine is absorbed by placing the rubber vibration isolator 7 between the engine 1 and a vehicle mounting part and the exhaust manifold 2 is adjacent to the rubber vibration isolator 7, two heat insulating boards 13, 14 dividing the rubber vibration isolator 7 from the exhaust manifold 2 are arranged between the rubber vibration isolator 7 and the exhaust manifold 2, the space 17 is made between the heat insulating board 13 and the heat insulating board 14 so as to enable ventilation, the heat from the exhaust manifold 2 is shut out by two heat insulating boards 13, 14, and heat radiation efficiency is obtained by the ventilation between the heat insulating boards 13, 14.
