PROBLEM TO BE SOLVED: To provide a sound insulation structure for a vehicle which secures good component mountability and inhibits vibrations of a component and a panel.SOLUTION: A sound insulation structure 1 for a vehicle comprises: a panel 20 which divides an interior part and an exterior part of a passenger compartment from each other; a component 30 positioned in the passenger compartment and fixed to a vehicle; and a sound absorbing material 10 sandwiched between the panel 20 and the component 30. A part of the sound absorbing material 10 has a deformed portion 12 which is pressed between the component 30 and the panel 20 and elastically compressed.SELECTED DRAWING: Figure 2
