To reduce noise.SOLUTION: A cover structure 100 comprises: a resin cover body 110 attached to an engine body 10; a plurality of insertion holes formed in the cover body 110; a plurality of collars 120 inserted into the insertion holes, connected to the cover body 110 and the engine body 10, and whose heights are different from each other; and a plurality of fastening members 130 inserted into the collars 120, and fastening the cover body 110 to the engine body 10. Thereby, vibration can be restrained from concentrating in a vibration concentration part of the cover body 110, and noise caused by the vibration transmitted from the engine body 10 can be restrained.SELECTED DRAWING: Figure 2 【課題】騒音を抑制する。【解決手段】カバー構造体１００は、エンジン本体１０に取り付けられる樹脂製のカバー本体１１０と、カバー本体１１０に形成された複数の挿通孔と、挿通孔に挿通され、カバー本体１１０およびエンジン本体１０と接続し、互いに高さが異なる複数のカラー１２０と、カラー１２０に挿通され、カバー本体１１０をエンジン本体１０に締結させる複数の締結部材１３０と、を備える。これにより、カバー本体１１０の振動集中部に振動が集中することを抑制することができ、エンジン本体１０から伝達される振動に起因する騒音を抑制することができる【選択図】図２
