To provide a sound insulation structure capable of improving sound insulation property while an increase of weight and cost is suppressed.SOLUTION: A sound insulation structure comprises: a mass section 11 which is arranged at an interval to an outer panel 5 for partitioning an internal space of a car body from outside and has a planar shape at least in a part; a plurality of spring sections 12 disposed on a side facing the outer panel 5 in the mass section 11; a leg section 17 whose one end 17a is connected to the mass section 11 and which extends toward the outer panel 5 from one end 17a to the other end 17b; and an attenuation section 18 disposed between the leg section 17 and the outer panel 5. The spring section 12 comprises: a hollow film member 14 having airtightness and flexibility; and gas 15 filled inside the film member 14.SELECTED DRAWING: Figure 3

    【課題】重量増加、コストの上昇を抑えつつ、遮音性を高めることのできる遮音構造を提供する。【解決手段】車体の内部空間と外部とを区画するアウターパネル5に対して間隔をあけて配置され、少なくとも一部に平面形状を有するマス部11と、マス部11においてアウターパネル5に対向する側に複数配置されたバネ部12と、一端17aがマス部11に接合され、一端17aから他端17bに向けてアウターパネル5に向かって延びる脚部17と、脚部17とアウターパネル5との間に設けられる減衰部18と、を備え、バネ部12は、気密性及び可撓性を有した中空の膜材14と、膜材14の内部に封入されたガス15と、を有する。【選択図】図3
