PROBLEM TO BE SOLVED: To achieve high soundproof performance in a simple configuration.SOLUTION: The soundproof structure of vehicle body includes an engine hood 1 constituting a vehicle body and a silencer 30 fixed on the engine hood 1. The silencer 30 and the engine hood 1 are joined to form an internal space L as the result of mutual surfaces being spaced from each other at any other part than a body part 20a formed on a hood inner 20 of the engine hood 1 through the body part 20a. The hood inner 20 is formed with a side wall 21 of a flange part 20d and the body part 20a serving as an opening O for communicating the internal space L with the outside.SELECTED DRAWING: Figure 1

    【課題】 簡易な構成にて車体の防音性能を向上させることを可能とする。【解決手段】 車体を構成するエンジンフード1と、エンジンフード1に固定されるサイレンサ30とを備え、サイレンサ30とエンジンフード1とは、エンジンフード1のフードインナ20上に形成された本体部20aを介して、互いの表面が本体部20a以外の部分で離隔してなる内部空間Lを形成するよう接合されており、フードインナ20には、内部空間Lと外部とを連通させる開口部Oとなるフランジ部20d及び本体部20aの側壁21が形成されている、車体の防音構造。【選択図】 図1
