Description
本発明のステアリングロック装置は、前述した従来から知られているステアリングロック装置と同様に、ステアリングコラムと、ステアリングシャフトと、キーロックカラーと、ロック用透孔と、ロックユニットとを備える。
このうちのステアリングコラムは、筒状で、車体に支持される。
又、前記ステアリングシャフトは、前記ステアリングコラムの内径側に回転自在に支持されている。
又、前記キーロックカラーは、前記ステアリングシャフトの一部に支持され、外周面に係合凹部を設けている。
又、前記ロック用透孔は、前記ステアリングコラムのうち、前記キーロックカラーと対向する部分に形成されている。
又、前記ロックユニットは、前記ステアリングコラムの外周面に当接する突き当て面を有し、この突き当て面に形成したガイド部を前記ロック用透孔の内側部分に配置した状態で、前記ステアリングコラムに支持されている。そして、イグニッションキーをＯＦＦした状態でこのロックユニットを構成するキーロックピンを径方向内方に変位させ、このキーロックピンの先端部を前記係合凹部に係合させる事により、前記ステアリングコラムの内径側での前記ステアリングシャフトの回転を抑える。
特に、本発明のステアリングロック装置に於いては、前記ステアリングコラムの外周面のうち前記ロック用透孔の周囲に、全周に亙り、又は周方向に関して間欠的に、突壁部を設けている。
The steering lock device of the present invention includes a steering column, a steering shaft, a key lock collar, a lock through hole, and a lock unit, similarly to the conventionally known steering lock device.
Among these, the steering column is cylindrical and is supported by the vehicle body.
The steering shaft is rotatably supported on the inner diameter side of the steering column.
The key lock collar is supported by a part of the steering shaft and has an engagement recess on the outer peripheral surface.
The lock through hole is formed in a portion of the steering column facing the key lock collar.
Further, the lock unit has an abutting surface that abuts on the outer peripheral surface of the steering column, and the steering column is arranged in a state in which a guide portion formed on the abutting surface is disposed on an inner portion of the locking through hole. It is supported by. Then, with the ignition key turned off, the key lock pin constituting the lock unit is displaced inward in the radial direction, and the tip end portion of the key lock pin is engaged with the engagement recess, whereby the steering column The rotation of the steering shaft on the inner diameter side is suppressed.
In particular, in the steering lock device according to the present invention, a protruding wall portion is provided around the lock through-hole on the outer peripheral surface of the steering column, or intermittently in the circumferential direction. .
又、本例の場合、前記ステアリングコラム２ｂの凹部１８、１８と、前記ロックユニット１２ａの突き当て面１９に設けた凸部２１、２１とを係合させている。この為、前記イグニッションキーをＯＦＦした状態で、前記ステアリングホイール４を大きな力で回転させようとした場合に、前記ステアリングシャフト３ａから前記ステアリングコラム２ｂに加わる力を効果的に分散させる事ができる。
更に、本例の場合、前記ステアリングコラム２ｂのうち、前記ロックユニット１２側の凸部２１、２１と係合する部分を有底の凹部１８、１８としている。この為、前述した特許文献２に記載の従来構造の様に、ステアリングコラムのうち、ロックユニット側の凸部と係合する部分を通孔とした場合と比較して、前記ステアリングコラム２ｂの強度及び剛性をより向上させる事ができる。
In this example, the concave portions 18 and 18 of the steering column 2b are engaged with the convex portions 21 and 21 provided on the abutting surface 19 of the lock unit 12a . Therefore, when the steering wheel 4 is rotated with a large force with the ignition key turned off, the force applied from the steering shaft 3a to the steering column 2b can be effectively dispersed.
Furthermore, in the case of this example, portions of the steering column 2b that engage with the convex portions 21 and 21 on the lock unit 12 side are formed as bottomed concave portions 18 and 18, respectively. Therefore, as in the conventional structure described in Patent Document 2 described above, the strength of the steering column 2b compared to the case where the steering column has a through-hole portion that engages with the convex portion on the lock unit side. In addition, the rigidity can be further improved.
Claims (1)
