Description

尚、前記インナコラム13bの後端寄り部分には、自動車の盗難防止の為に、前記ステアリングホイール1の操作を実質的に不能にするステアリングロック装置を組み込む為のロック用透孔58を設けている。これと共に、前記アウタコラム12bのうちで、軸方向位置がこのロック用透孔58と整合する部分に、キーロックカラー59を外嵌している。前記ステアリングロック装置は、前記ロック用透孔58の内側に、ロックユニット(図示省略)の先端部を配置した状態で、このロックユニットを前記インナコラム13bに支持固定する。イグニッションキーをOFFして、このロックユニットを構成するロックピンを径方向内方に変位させ、このロックピンと前記キーロックカラー59の外周面に形成した係合凹部とを係合させる事で、前記ステアリングシャフト5bの回転を実質的に不能にする(前記ステアリングホイール1を、通常の運転姿勢のまま操作する程度の力では、前記ステアリングシャフト5bが回転しない様にする)。
In addition, a lock through hole 58 for incorporating a steering lock device that substantially disables the operation of the steering wheel 1 is provided in a portion near the rear end of the inner column 13b to prevent theft of the automobile. Yes. At the same time, a key lock collar 59 is externally fitted to a portion of the outer column 12b where the axial position is aligned with the lock through hole 58. The steering lock device supports and fixes the lock unit to the inner column 13b in a state where the tip of a lock unit (not shown) is disposed inside the lock through hole 58. By turning off the ignition key, displacing the lock pin constituting the lock unit radially inward, and engaging the lock pin with the engagement recess formed on the outer peripheral surface of the key lock collar 59, the The rotation of the steering shaft 5b is substantially disabled (the steering shaft 5b is prevented from rotating with a force sufficient to operate the steering wheel 1 in a normal driving posture).

上述の様な本例のテレスコピック式ステアリングコラム装置によれば、前記ステアリングホイール1を調節後の位置に保持する力を安定させる事ができる。
即ち、本例の場合、前記両被挟持部17a、17aの外側面の上下前後の四隅部に、幅方向外方に突出する凸部41、41を形成している。この為、前記ステアリングホイール1を調節後の位置に保持すべく、前記被駆動側カム32aと前記押圧プレート39との間隔を縮めた状態では、前記各凸部41、41の先端面が、前記両摩擦板ユニット46、46を介して、前記支持ブラケット20aの両内側面(前記両支持板部23a、23aの内側面)と当接する。従って、本例の場合には、前記ステアリングホイール1を調節後の位置に保持した状態で、前記両摩擦板ユニット46、46を介して互いに当接する、前記各凸部41、41の先端面と前記両支持板部23a、23aの内側面との当接部の面積を、前述の図15〜17に示した従来構造の第2例の様に、1対の支持板部23、23の内側面と変位ブラケット18の両側面(1対の被挟持部17、17の外側面)とを、互いに対向する部分のほぼ全面で当接させる構造と比較して小さくできる。この結果、前記両摩擦板ユニット46、46を介して互いに当接する、前記各凸部41、41の先端面と前記両支持板部23a、23aの内側面との当接部の面圧を大きくできると共に、当接状態がばらつくのを抑えられる。
According to the above such telescopic copy Locking type steering column apparatus of the present embodiment, the force for holding the steering wheel 1 to the adjusted position can be stabilized.
That is, in the case of this example, convex portions 41 and 41 projecting outward in the width direction are formed at the upper and lower four corners of the outer surface of the sandwiched portions 17a and 17a. For this reason, in a state where the distance between the driven cam 32a and the pressing plate 39 is shortened so as to hold the steering wheel 1 in the adjusted position, the tip surfaces of the convex portions 41, 41 are Via both friction plate units 46 and 46, it contacts both inner side surfaces of the support bracket 20a (inner side surfaces of the both support plate portions 23a and 23a). Therefore, in the case of this example, with the steering wheel 1 held at the adjusted position, the front end surfaces of the convex portions 41, 41 that are in contact with each other via the friction plate units 46, 46, and The area of the abutting portion with the inner side surface of both the support plate portions 23a, 23a is the same as that of the pair of support plate portions 23, 23 as in the second example of the conventional structure shown in FIGS. The side surface and both side surfaces of the displacement bracket 18 (the outer surfaces of the pair of sandwiched portions 17 and 17) can be made smaller than a structure in which substantially the entire surfaces facing each other are brought into contact with each other. As a result, the contact pressure between the tip surfaces of the convex portions 41 and 41 and the inner side surfaces of the support plate portions 23a and 23a, which are in contact with each other via the friction plate units 46 and 46, is increased. It is possible to suppress the contact state from being varied.

又、前記両円孔19a、19aの幅方向外端部を、前記両被挟持部17a、17aの外側面のうち、前記各凸部41、41に囲まれた中央部に開口させ、前記両円孔19a、19aに挿通した前記調節ロッド27aのうち、前記両支持板部23a、23aの外側面から突出した部分の周囲に、それぞれが押圧部である、前記被駆動側カム32aと前記押圧プレート39とを設けている。従って、前記ステアリングホイール1を調節後の位置に保持すべく、前記被駆動側カム32aと前記押圧プレート39との間隔を縮めた状態で、これら被駆動側カム32a及び押圧プレート39と前記支持板部23a、23aの外側面との当接部と、(前記両摩擦板ユニット46、46を介して互いに当接する、)これら両支持板部23a、23aの内側面と前記各凸部41、41の先端面との当接部との距離を大きくする事ができる。この為、前記被駆動側カム32aと前記押圧プレート39との間隔を縮める事に伴って、前記両支持板部23a、23aの内側面と前記各凸部41、41の先端面との間に作用するモーメントを大きくする事ができる。従って、前記両支持板部23a、23aの内側面と前記各凸部41、41の先端面との当接部の面圧をより大きくできる。更に、前記摩擦ユニット46、46を介して互いに対向する、前記両被挟持板部17a、17aの外側面と前記両支持板部23a、23aの内側面との対向部のうち、前記調節ロッド27aの周囲に幅方向の隙間が存在した状態となる。従って、前記被駆動側カム32aと前記押圧プレート39との間隔を縮めた状態で、前記両支持板部23a、23aを幅方向に弾性変形し易くでき、前記アウタコラム12bの内径が後方に向かう程小さくなる様に弾性変形する程度を緩和できる。即ち、前記両被挟持部17a、17aの外側面同士をほぼ平行に保ったまま、前記アウタコラム12bの後端寄り部分の内径を縮径させる事ができる。この為、前記調節ロッド27aが略V字形又は弓形に弾性変形するのを抑えられ、この調節ロッド27aの両端部に設けた、前記被駆動側カム32aと前記押圧プレート39との間隔を縮めて、前記両支持板部23a、23aの内側面により、前記両摩擦ユニット46、46を介して前記両被挟持部17a、17aの外側面(前記各凸部41、41の先端面)を押え付ける力を十分に発揮させられる。この結果、前記ステアリングホイール1を調節後の位置に保持する力を安定して大きくする事ができる。
Further, the outer ends in the width direction of both the circular holes 19a, 19a are opened in the center portion surrounded by the respective convex portions 41, 41 on the outer surfaces of the both sandwiched portions 17a, 17a. Of the adjusting rod 27a inserted through the circular holes 19a, 19a, the driven cam 32a and the pressing member, each of which is a pressing portion, are disposed around portions protruding from the outer surfaces of the support plate portions 23a, 23a. A plate 39 is provided. Accordingly, in order to hold the steering wheel 1 in the adjusted position, the driven cam 32a, the pressing plate 39, and the support plate in a state where the distance between the driven cam 32a and the pressing plate 39 is reduced. Abutting portions with the outer side surfaces of the portions 23a and 23a, inner surfaces of the supporting plate portions 23a and 23a (which abut against each other via the friction plate units 46 and 46), and the convex portions 41 and 41, respectively. It is possible to increase the distance from the abutting portion with the tip surface. For this reason, as the distance between the driven cam 32a and the pressing plate 39 is reduced, the inner surface of the support plate portions 23a, 23a and the front end surface of the convex portions 41, 41 are provided. The acting moment can be increased. Therefore, the surface pressure of the contact portion between the inner side surfaces of the support plate portions 23a and 23a and the tip surfaces of the convex portions 41 and 41 can be increased. Further, among the opposing portions between the outer side surfaces of the both sandwiched plate portions 17a and 17a and the inner side surfaces of the two supporting plate portions 23a and 23a, which are opposed to each other via the friction plate units 46 and 46, the adjustment rod A gap in the width direction exists around 27a. Accordingly, the support plate portions 23a and 23a can be easily elastically deformed in the width direction in a state where the distance between the driven cam 32a and the pressing plate 39 is reduced, and the inner diameter of the outer column 12b is directed rearward. The degree of elastic deformation can be reduced so as to become smaller. That is, the inner diameter of the portion near the rear end of the outer column 12b can be reduced while the outer surfaces of the sandwiched portions 17a and 17a are kept substantially parallel to each other. Therefore, the adjustment rod 27a is prevented from being elastically deformed into a substantially V shape or an arcuate shape, and the distance between the driven cam 32a and the pressing plate 39 provided at both ends of the adjustment rod 27a is reduced. The inner surfaces of the support plate portions 23a and 23a hold the outer surfaces of the sandwiched portions 17a and 17a (tip surfaces of the convex portions 41 and 41) through the friction plate units 46 and 46, respectively. The power to attach can be fully demonstrated. As a result, the force for holding the steering wheel 1 in the adjusted position can be stably increased.
