PROBLEM TO BE SOLVED: To provide a sound insulation structure which can inhibit noise from entering into a vehicle cabin through a first opening formed at a panel partitioning the vehicle cabin interior from the vehicle cabin exterior.SOLUTION: A sound insulation structure 7 includes: a plate-like member 71 having an opening 71a; a first elastic member 72 which is disposed at the lower surface side of the plate-like member 71 and formed so as to cover the opening 71a; and a second elastic member 73 which is disposed at the upper surface side of the plate-like member 71 and formed so as to cover the opening 71a. Through holes 71b are formed around the opening 71a in the plate-like member 71. Projection parts 72a which are inserted into the through holes 71b are formed at the first elastic member 72. Through holes 73a into which the projection parts 72a are inserted are formed at the second elastic member 73. An engagement part 72b, which engages with the second elastic member 73 in a state where the projection parts 72a are inserted into the through holes 71b and 73a, is formed at each projection part 72a.SELECTED DRAWING: Figure 6

    【課題】車室内と車室外とを区画するパネルに形成された第1開口部を介して車室内にノイズが入るのを抑制することが可能な遮音構造体を提供する。【解決手段】遮音構造体7は、開口部71aを有する板状部材71と、板状部材71の下面側に配置され、開口部71aを覆うように形成された第1弾性部材72と、板状部材71の上面側に配置され、開口部71aを覆うように形成された第2弾性部材73とを備える。板状部材71には、開口部71aの周囲に貫通孔71bが形成されている。第1弾性部材72には、貫通孔71bに挿入される突起部72aが形成されている。第2弾性部材73には、突起部72aが挿入される貫通孔73aが形成されている。突起部72aには、突起部72aが貫通孔71bおよび73aに挿入された状態で、第2弾性部材73と係合する係合部72bが形成されている。【選択図】図6
