To provide a column hole cover which can assure sealability between itself and a housing while reducing a size of a part of the column hole cover to be fitted to the housing, and a steering device comprising the same.SOLUTION: A column hole cover 6, which is located between a housing 4 which accommodates a pinion shaft 23 which is rotated according to a steering operation of a steering wheel 10 and a dash panel 7 which partitions the interior and the exterior of a cabin, and which is fitted to a fitted part 422a of the housing 4 and seals an insertion port 70 provided in the dash panel 7, comprises: a cylindrical part 61 which is located outside the fitted part 422a; an annular sealing part 63 which contacts the dash panel 7; and a tubular part 62 which is provided between the cylindrical part 61 and the sealing part 63, and is elastically compressed between the housing 4 and the dash panel 7. The tubular part 62 has a seal area 62a, and the seal area 62a is pressed onto an apical surface of the fitted part 422a by a restitutive force of the tubular part 62 itself.SELECTED DRAWING: Figure 3A
【課題】コラムホールカバーにおけるハウジングへの取り付け部分を小型化しながらも、ハウジングとの間のシール性を確保することが可能なコラムホールカバー及びこれを備えたステアリング装置を提供する。【解決手段】ステアリングホイール10の操舵操作に応じて回転するピニオンシャフト23を収容するハウジング4と車室内外を区画するダッシュパネル7との間に配置され、ハウジング4の被嵌合部422aに嵌合されてダッシュパネル7に設けられた挿通口70を封止するコラムホールカバー6は、被嵌合部422aの外側に配置される円筒部61と、ダッシュパネル7に当接する環状の封止部63と、円筒部61と封止部63との間に設けられ、ハウジング4とダッシュパネル7との間で弾性圧縮される筒状部62とを備える。筒状部62は、シール面62aを有し、シール面62aが筒状部62自体の復元力によって被嵌合部422aの先端面に押し付けられる。【選択図】図3A
