To effectively prevent a possibility of falling of a cover member while attaining excellent insertion workability of a cylindrical member into the cover member.SOLUTION: A soundproof member 1 comprises a cylindrical member 2 covering a part of an object extending in a front-back direction, and a cover member 3 covering an outside of the cylindrical member 2. The cylindrical member 2 is formed from resin foam and has a first insertion hole 4 penetratingly formed in the front-back direction and allowing the object to be inserted thereinto. The cover member 3 is formed from a resin and has a second insertion hole 6 penetrating in the front-back direction and allowing the cylindrical member 2 to be inserted thereinto. In a state that the object is not penetrated into the cylindrical member 2, gaps 10, 10 extending in the front-back direction are formed between the external surface of the cylindrical member 2 and the internal surface of the cover member 3, and in a state that the object is inserted into the cylindrical member 2, the gaps 10, 10 are closed due to contact between the external surface of the cylindrical member 2 and the internal surface of the cover member 3.SELECTED DRAWING: Figure 1

    【課題】筒状部材のカバー部材への挿入作業性を良好としつつ、カバー部材の脱落のおそれも効果的に防止する。【解決手段】防音部材1は、前後方向に延びる対象物の一部を覆う筒状部材2と、筒状部材2の外側を覆うカバー部材3とからなる。筒状部材2は、発泡樹脂で形成され、前後方向に貫通形成されて対象物が挿通可能な第1挿通孔4を有し、カバー部材3は、樹脂で形成され、前後方向に貫通して筒状部材2が挿通可能な第2挿通孔6を有する。そして、筒状部材2に対象物が挿通されない状態では、筒状部材2の外面とカバー部材3の内面との間に、前後方向に延びる隙間10,10が形成され、筒状部材2に対象物が挿通された状態では、筒状部材2の外面とカバー部材3の内面とが接触して隙間10,10が閉塞される。【選択図】図1
