To suppress the intrusion of noise into a cabin from the outside of the cabin.SOLUTION: A steering shaft 5 penetrates a collar penetration hole 33 defined by a collar internal peripheral face 32 of an annular collar 30. A lower cover 20 is an elastic body integrally having a collar support part 21, a flange part 22 and a surrounding part 23. The collar support part 21 face-contacts with a collar external peripheral face 31, and tightly adheres thereto, and the flange part 22 is fixed to a panel 4 while being tightly overlapped thereon at the outside of an entire peripheral edge of a shaft insertion hole 11 of the panel 4. The surrounding part 23 is diameter-contracted in a funnel shape from the flange part 22 toward the collar support part 21, and blocks a clearance between the collar support part 21 and the flange part 22. The collar support part 21 fixedly supports the collar 30. The collar 30 is permitted in relative rotation with a steering shaft 5, and engaged with the steering shaft 5 so as to be prohibited in relative movement in an axial direction in a state that the collar internal peripheral face 32 and the external peripheral face of the steering shaft 5 approximate each other, or contact with each other.SELECTED DRAWING: Figure 2

    【課題】車室外から車室内への騒音の侵入を抑制する。【解決手段】カラー30のカラー内周面32が区画するカラー貫通孔33をステアリングシャフト5が挿通する。ロアカバー20はカラー支持部21とフランジ部22と包囲部23とを一体的に有する弾性体である。カラー支持部21はカラー外周面31に面接触して密着し、フランジ部22はパネル4のシャフト挿通孔11の全周縁の外側でパネル4に重なって密閉状に固定される。包囲部23はフランジ部22からカラー支持部21に向かって漏斗状に縮径してカラー支持部21とフランジ部22との間を塞ぐ。カラー支持部21はカラー30を固定的に支持する。カラー30はカラー内周面32とステアリングシャフト5の外周面とが近接又は接触した状態で、ステアリングシャフト5との相対回転が許容され且つ軸方向の相対移動が禁止されるようにステアリングシャフト5と係合する。【選択図】図2
