Claims (8)
- 山部と谷部を連設した蛇腹筒部を有しており、該蛇腹筒部がサスペンション機構を構成するショックアブソーバのピストンロッドに外挿されるようになっていると共に、該蛇腹筒部の軸方向両側が該ショックアブソーバの該ピストンロッドとシリンダとの各一方に取り付けられるようにされている樹脂製のダストカバーにおいて、
前記蛇腹筒部の軸方向一端側には嵌合筒部が設けられていると共に、該嵌合筒部には内周面に開口する周溝が形成されており、前記シリンダから外周側に突出する係止爪が該周溝に対して該嵌合筒部の開口部から嵌め入れられるようになっている一方、
該嵌合筒部において外周側へ突出して内周側へ開口する山形断面をもって軸方向に延びる屈曲部を形成し、該屈曲部の周方向への弾性的な拡開変形により該嵌合筒部が実質的に拡径されるようにしたことを特徴とするダストカバー。 - 前記嵌合筒部の周方向で互いに離隔して前記屈曲部が複数設けられている請求項1に記載のダストカバー。
- 複数の前記屈曲部において、それぞれの内周側への開口幅が略同じに設定されている請求項2に記載のダストカバー。
- 前記屈曲部として、外周側への突出寸法が大きい主変形部と、外周側への突出寸法が小さい副変形部とが設けられている請求項2又は3に記載のダストカバー。
- 前記蛇腹筒部の軸方向端部の傾斜面から前記屈曲部が軸方向に延び出した状態で、該屈曲部が該蛇腹筒部とつながって形成されている請求項1〜4の何れか1項に記載のダストカバー。
- 前記屈曲部が前記嵌合筒部の径方向に突出していると共に、該屈曲部の周方向両側部分が互いに突出方向を対称面とする面対称形状とされている請求項1〜5の何れか1項に記載のダストカバー。
- 前記嵌合筒部が、径方向で互いに型割りされる複数の分割金型を用いてブロー成形されたものであり、前記屈曲部の外周面が何れも型割り方向でアンダーカットにならない傾斜角度をもって形成されている請求項1〜6の何れか1項に記載のダストカバー。
- 前記係止爪が該嵌合筒部の開口部に対する嵌入方向先端側に向かって次第に内周側に傾斜するテーパ形状とされている請求項1〜7の何れか1項に記載のダストカバー。
