Description
本発明は、車体のダッシュパネルに貫設された取付孔及びこの取付孔に挿通されるステアリングシャフトの一部を覆うように、該取付孔に一端が取り付けられるとともに、該ステアリングシャフトが連結されたギアハウジングに他端が取り付けられるコラムホールカバーに関する。 In the present invention, one end is attached to the mounting hole so as to cover a mounting hole penetrating the dash panel of the vehicle body and a part of the steering shaft inserted through the mounting hole, and the steering shaft is connected. The present invention relates to a column hole cover whose other end is attached to a gear housing.
車両のステアリング機構では、ステアリングシャフトを介してステアリングホイールの回転力をステアリングギヤに伝達し、この回転力をタイロッドの左右方向運動に変換することで車輪の制御を行っている。ここで、ステアリングホイールは車室内にある一方、ステアリングギヤは車体の外（エンジン室）にあり、ステアリングシャフトは車体の内側から外側に延びている。従って、通常、ステアリングシャフトは運転席の足元近くのダッシュパネルに設けられた孔を貫通しているため、走行中に車両の外部から泥や水などが孔を介して車室内に入ってきてしまうおそれがある。そこで、通常、ゴムなどの弾性材料よりなるコラムホールカバーでこの貫通孔を覆って、外部から泥や水などが車室内に侵入しないようにしている。 In a vehicle steering mechanism, the rotational force of a steering wheel is transmitted to a steering gear via a steering shaft, and the wheel is controlled by converting this rotational force into a lateral movement of a tie rod. Here, while the steering wheel is in the vehicle interior, the steering gear is outside the vehicle body (engine chamber), and the steering shaft extends from the inside to the outside of the vehicle body. Therefore, since the steering shaft normally passes through a hole provided in the dash panel near the feet of the driver's seat, mud, water, and the like enter the vehicle compartment through the hole during traveling. There is a fear. Therefore, the through hole is usually covered with a column hole cover made of an elastic material such as rubber so that mud, water and the like do not enter the vehicle interior from the outside.
このようなコラムホールカバーとして、図６に示されるように、両端に開口を有する筒状の本体部１３０と、この本体部１３０の一端側に一体に設けられた嵌合部１３５と本体部１３０の他端側に一体に設けられた第２嵌合部１３２とを有するコラムホールカバー１０１が知られている（例えば、特許文献１、図２１参照）。 As such a column hole cover, as shown in FIG. 6, a cylindrical main body portion 130 having openings at both ends, a fitting portion 135 and a main body portion 130 provided integrally on one end side of the main body portion 130. A column hole cover 101 having a second fitting portion 132 provided integrally on the other end side of this is known (see, for example, Patent Document 1 and FIG. 21).
このコラムホールカバー１０１の取付作業は、例えば、以下のようにして行われる。作業者は、ステアリングシャフト１２１が連結されたギヤハウジング１２０に第２嵌合部１３２を嵌合などにより取り付けた後、車体の外側からこれらを持ち上げる。そして、室内側すなわち図６にてダッシュパネル１１０の右上方から手を差し込み、嵌合部１３５の嵌合部押さえ部１３５ｂを摘んで嵌合部溝１３５ａの一箇所を拡げてパネル内縁部１１１に嵌め込む。次に隣接する嵌合部溝１３５ａを拡げて順にパネル内縁部１１１に嵌め合わせてゆき、嵌合部溝１３５ａとパネル内縁部１１１とを全周に亘って嵌め合わせて取付作業を完了する。しかしながら、上記従来の構成よりなるコラムホールカバー１０１では、組付け誤差の吸収やギヤハウジング１２０の振動による軸ズレの吸収をする為に、蛇腹部１３６が形成されている。一般に、蛇腹部１３６は伸縮性・追従性を確保しようとすると、その膜厚が薄くなる為、エンジン室側からの騒音が透過しやすい傾向にある。 The column hole cover 101 is attached as follows, for example. The worker lifts them from the outside of the vehicle body after attaching the second fitting portion 132 to the gear housing 120 to which the steering shaft 121 is connected by fitting or the like. Then, a hand is inserted from the upper right side of the dash panel 110 in the indoor side, that is, in FIG. Fit. Next, the adjacent fitting portion groove 135a is expanded and fitted into the panel inner edge portion 111 in order, and the fitting portion groove 135a and the panel inner edge portion 111 are fitted over the entire circumference to complete the mounting operation. However, in the column hole cover 101 having the above-described conventional configuration, the bellows portion 136 is formed in order to absorb the assembly error and the shaft displacement due to the vibration of the gear housing 120. In general, when the bellows portion 136 is intended to ensure stretchability and followability, the film thickness is reduced, and therefore noise from the engine compartment side tends to be transmitted.
本発明は、上記従来技術の問題を解決するものであり、エンジン室側から車室内への透過音を減少し且つ蛇腹の伸縮性を備えたコラムホールカバーを提供することを目的とする。 SUMMARY OF THE INVENTION The present invention solves the above-described problems of the prior art, and an object of the present invention is to provide a column hole cover that reduces transmitted sound from the engine compartment side to the vehicle compartment and has bellows elasticity.
本発明は、一端に第１開口を他端に第２開口を有する筒状の本体部と、該本体部の前記一端側に設けられ、車体のダッシュパネルに貫設された取付孔を覆うように該ダッシュパネルに嵌着されるパネル取付部と、該本体部の前記他端側に設けられ、ギヤハウジングに取り付けられるギヤ取付部とからなり、前記本体部を伸縮可能とする蛇腹部を有するコラムホールカバーであって、前記蛇腹部の内側空間に吸音材を配置し、前記蛇腹部の根元部には該吸音材を保持する脱落防止突起を設けたことを特徴とする。 The present invention covers a cylindrical main body having a first opening at one end and a second opening at the other end, and an attachment hole provided on the one end side of the main body and penetrating through the dash panel of the vehicle body. A panel mounting portion that is fitted to the dash panel, and a gear mounting portion that is provided on the other end side of the main body portion and is attached to a gear housing, and has a bellows portion that allows the main body portion to expand and contract. The column hole cover is characterized in that a sound absorbing material is disposed in an inner space of the bellows portion, and a drop-off preventing projection for holding the sound absorbing material is provided at a root portion of the bellows portion.
コラムホールカバー１には、本体部１０の蛇腹部１３の内側空間に吸音材４０を配置している。この為、薄膜となる蛇腹部１３からの透過音が低減でき、遮音性が向上できる。また、吸音材４０は軟質材である為、蛇腹部１３の伸縮・追従性にほとんど影響を与えない。さらに、蛇腹部１３の根元部には脱落防止突起１４が形成されている。この為、吸音材４０が蛇腹部１３の内側空間へ安定的に保持される。
好ましくは吸音材４０には、吸音材４０より硬質の芯４３が埋設されていると良い。吸音材４０を蛇腹部１３の内側空間に挿入し易く、組付け作業性が向上する。
In the column hole cover 1, a sound absorbing material 40 is disposed in the inner space of the bellows portion 13 of the main body portion 10. For this reason, the transmitted sound from the bellows part 13 used as a thin film can be reduced, and sound insulation can be improved. Further, since the sound absorbing material 40 is a soft material, it hardly affects the stretchability / following performance of the bellows portion 13. Further, a drop-off preventing projection 14 is formed at the base portion of the bellows portion 13. For this reason, the sound absorbing material 40 is stably held in the inner space of the bellows portion 13.
Preferably, a core 43 that is harder than the sound absorbing material 40 is embedded in the sound absorbing material 40. The sound absorbing material 40 can be easily inserted into the inner space of the bellows portion 13, and the assembly workability is improved.

For example, the gear mounting portion 30 may be formed of a synthetic resin having higher rigidity than other portions. The gear attachment portion 30 is attached to a gear housing (not shown) by fitting or the like.
本体部１０は、一端側に第１開口１１を有するとともに他端側に第２開口１２を有する筒状部材である。図１に示されるように第１開口は楕円形状であり、第２開口は円形状である。このため、パネル取付部２０もその横断面形状が略楕円形状とされており、ギヤ取付部３０もその横断面形状が円形状（真円又は略真円）とされている。 The main body 10 is a cylindrical member having a first opening 11 on one end side and a second opening 12 on the other end side. As shown in FIG. 1, the first opening has an elliptical shape, and the second opening has a circular shape. Therefore, the cross-sectional shape of the panel mounting portion 20 is also substantially elliptical, and the cross-sectional shape of the gear mounting portion 30 is also circular (perfect circle or substantially perfect circle).
パネル取付部２０は、車体のダッシュパネル２の取付孔３を覆うように、この取付孔３の周りのパネル内縁部４に取り付けられる。このパネル取付部２０は、パネル取付部２０がダッシュパネル２のパネル内縁部４に取り付けられた取付状態における取付形状と略同等の成形形状となるように、ゴム弾性体により一体成形されたものである。すなわち、嵌合溝部内にパネル内縁部が嵌め合い代を持って嵌め込むように形成されている。 The panel attachment portion 20 is attached to the panel inner edge portion 4 around the attachment hole 3 so as to cover the attachment hole 3 of the dash panel 2 of the vehicle body. The panel mounting portion 20 is integrally formed of a rubber elastic body so that the panel mounting portion 20 has a molding shape substantially equivalent to the mounting shape in the mounting state in which the panel mounting portion 20 is mounted on the panel inner edge portion 4 of the dash panel 2. is there. That is, the inner edge of the panel is formed in the fitting groove with a fitting margin.
