To provide a vehicle sound insulation structure capable of certainly attaching a sound shielding cover even if attaching/detaching work is repeatedly carried out, and facilitating the attaching/detecting work.SOLUTION: A vehicle sound insulation structure is equipped with a soft sound insulation cover 21 provided on noise radiation members (7 and 11) of a vehicle radiating noise; a screw member 26 for fixing the sound insulation cover 21 to a noise radiation members; and a spacer 30 which is provided on the sound insulation cover 21 and has a through-hole 30A inserted in a shaft portion 28B of the screw member 26. The spacer 30 has a first member 31 equipped with an inner cylinder portion 33 forming the through-hole 30A and a first flange 34 abutting on one surface of the sound insulation cover 21; and a second member 32 equipped with an outer cylinder portion 35 fitted with the outside of the inner cylinder 33 and a second flange 36 abutting on the other surface of the sound insulation cover 21. The first member 31 and the second member 32 are integrated with one another while making the outer cylinder portion 35 abut on the first flange 34.SELECTED DRAWING: Figure 4

    【課題】着脱作業が繰り返し行われても、遮音カバーを確実に取り付けることができ、且つ遮音カバーの着脱作業が容易な車両の遮音構造を提供する。【解決手段】騒音を放射する前記車両の騒音放射部材(7、11)に設けられる軟質の遮音カバー21と、遮音カバー21を騒音放射部材に固定するためのねじ部材26と、遮音カバー21に設けられ、ねじ部材26の軸部28Bを挿通させる貫通孔30Aを有するスペーサ30とを備え、スペーサ30は、貫通孔30Aを形成する内筒部33及び遮音カバー21の一方の面に当接する第1フランジ34を備える第1部材31と、内筒部33の外側に嵌着する外筒部35及び遮音カバー21の他方の面に当接する第2フランジ36を備える第2部材32とを有し、第1部材31及び第2部材32は、外筒部35を第1フランジ34に当接させた状態で互いに一体とされる。【選択図】図4
