To provide a dust cover which can shield sounds which enter a passenger compartment from an engine room to improve quietness, and to provide a manufacturing method of the dust cover.SOLUTION: A dust cover includes: a cylindrical bush attached to an outer peripheral surface of a second steering shaft penetrating through a dash panel and extending in an axial direction; and a first bellows and a second bellows disposed between the dash panel and the bush and have annular shapes. The first bellows includes a first flexible part protruding to one side in the axial direction. The second bellows includes a second flexible part protruding to the other side in the axial direction. The first flexible part has one curve part protruding to the one side in the axial direction, and the second flexible part has one curve part protruding to the other side in the axial direction.SELECTED DRAWING: Figure 4
【課題】エンジンルームから車室へ入る音を遮蔽して車室の静音性をより高くするダストカバーおよびダストカバーの製造方法を提供すること。【解決手段】ダストカバーは、ダッシュパネルを貫通して軸方向に延びる第2ステアリングシャフトの外周面に取り付けられる筒状のブッシュと、ダッシュパネルとブッシュとの間に配置される環状の第1ベローズおよび第2ベローズと、を備える。第1ベローズは、軸方向の一方側に凸となる第1可撓部を備え、第2ベローズは、軸方向の他方側に凸となる第2可撓部を備える。第1可撓部においては、軸方向の一方側に凸となる湾曲部が1つであり、第2可撓部においては、軸方向の他方側に凸となる湾曲部が1つである。【選択図】図4
