Summary:To provide a dust cover that is less likely to generate a gap between a seal part and a steering shaft.SOLUTION: A dust cover includes: a cylindrical bushing fitted to an outer peripheral surface of a steering shaft and extending along a circumferential direction about a central axis; and a bellows for blocking a gap between a cylindrical member and the bushing. The bellows includes a seal part projecting toward the outer peripheral surface of a steering shaft and including a tip that abuts on the outer peripheral surface. The bellows is softer than the bushing.SELECTED DRAWING: Figure 5 【課題】シール部とステアリングシャフトとの間に隙間が生じにくいダストカバーを提供すること。【解決手段】ダストカバーは、ステアリングシャフトの外周面に取り付けられ且つ中心軸の軸回りの周方向に沿って延びる筒状のブッシュと、筒状部材とブッシュとの間の隙間を塞ぐベローズと、を備える。ベローズは、ステアリングシャフトの外周面に向けて突出し且つ先端が外周面に当接するシール部を含み、ベローズはブッシュよりも軟らかい。【選択図】図５
