PROBLEM TO BE SOLVED: To provide a technology to sufficiently reduce noise propagating into a cabin through a through-hole of a dash panel.SOLUTION: There is provided a cover structure for a steering shaft extending to an engine room through a through-hole formed in a dash panel. The cover structure includes a cylindrical part into which the steering shaft is inserted, a first flange plate protruding outward from the peripheral surface of the cylindrical part, a second flange plate protruding outward from the peripheral surface of the cylindrical part at a position separated from the first flange plate in the extending direction of the steering shaft, and a seal member having a pressure-contact part that is brought into pressure contact with the dash panel by the first flange plate. Space is formed between the first flange plate and the second flange plate. The seal member includes a closing part adjacent to the outer peripheral edges of the first flange plate and the second flange plate, extending from the pressure-contact part so as to close the space surrounded by the cylindrical part, the first flange plate and the second flange plate.SELECTED DRAWING: Figure 2

    【課題】ダッシュパネルの貫通孔を通じて車室内へ伝播するノイズを十分に低減する技術を提供することを目的とする。【解決手段】本出願は、ダッシュパネルに形成された貫通孔を通じてエンジンルーム内に延びるステアリングシャフト用のカバー構造を開示する。カバー構造は、ステアリングシャフトが挿通される筒部と、筒部の周面から外方に突出する第1鍔板と、ステアリングシャフトの延設方向において第1鍔板から離間した位置で筒部の周面から外方に突出する第2鍔板と、第1鍔板によって、ダッシュパネルに圧接される圧接部を有するシール部材と、を備える。第1鍔板と第2鍔板との間には、空間が形成される。シール部材は、第1鍔板及び第2鍔板の外周縁に隣接し、筒部、第1鍔板及び第2鍔板によって囲まれた空間を閉じるように圧接部から延接された閉塞部を含む。【選択図】図2
