PROBLEM TO BE SOLVED: To provide a sound insulation device for an internal combustion engine that can suppress noise and heat damage.SOLUTION: A sound insulation device for an internal combustion engine includes: a sound insulation material for covering an internal combustion engine and having an opening/closing part capable of opening/closing; and a control part for closing the opening/closing part when a level of the sound emitted from the internal combustion engine is larger than or equal to a predetermined loudness and opening the opening/closing part when the level of the sound is smaller than the predetermined loudness. Accordingly, the sound insulation device for an internal combustion engine can suppress noise and heat damage.SELECTED DRAWING: Figure 1
