置が破壊されて、ハンドルを自由に回動させることがで
きるので車を盗まれるという欠点があった。Conventionally, in this type of device, when a key inserted into a cylinder lock is removed, a locking rod protrudes and locks onto a shaft in a steering column, thereby preventing rotation of the steering wheel. Although this prevents theft by preventing the handle from turning, it is still possible to prevent theft from occurring by hanging a crowbar or other tool on the handle.
If the steering wheel was forcibly turned, the steering lock device would be destroyed and the steering wheel could be turned freely, which could lead to the car being stolen.

したステアリングロックの破壊防止装置にある。The present invention has been made by focusing on such drawbacks, and its purpose is to prevent the steering device from being destroyed even when the steering wheel is forcibly turned by a tool or the like. A slidable pipe with a rack formed on the periphery is fitted into the shaft to which the handle is fixed and a pin is implanted, and this pipe is constantly urged in the axial direction by a spring. When the locking rod that protrudes when the key is removed from the cylinder lock is inserted into the elongated hole formed in the pipe, that is, when the handle is forcibly rotated while the lock is locked, the pin and rack may be pressed against the spring. To provide a destruction prevention device for a steering lock, which slides in the axial direction without bending the locking rod while resisting, and also prevents smooth operation of the handle.

と・・ンドルＢが共に回動する。FIG. 1 is a diagram showing one embodiment of the fraudulent means, and A is a tool that is hung on the handle B to forcibly rotate the handle B. C is a steering column. A shaft 1 is fitted inside this steering column C. One end of this shaft 1 (FI... is fixed to a steering wheel B, and the other end is connected to a steering axle (not shown). D is a steering lock device, and a cross-sectional view of the main part of this device is shown in the second figure.
As shown in the figure, to explain the outline, 2 is a housing of a steering lock device, and a cylinder lock 3 inside this housing 2 is rotatably operated by a key (not shown).
, a check lever 4 that operates when the key is inserted into/removed from the cylinder lock 3, and a rotating cam 5 that rotates when the rotor (not shown) of the cylinder lock 3 rotates with the rotation of the key.
A hanger 6 engaged with the rotating cam 5, a spring 7 that always holds the hanger 6, and a locking rod 8 fixed to the hanger 6 are provided, and the locking rod 8 unlocks the rotating cam 5. When the lever 6 is moved backward while rotating in the locking direction, the shaft 1 is fitted against the spring 7 and detached from the groove 9' of the pipe 9.

Further, the locking rod 8 is inserted into the elongated hole 14 formed in the axial direction of the pipe 12 and the pipe 12 is locked. , when the shaft 1 is rotated together with the handle B while the lock is locked, the pin 13 slides on the surface of the pipe 1

ック装置の破損も防止できるという効果を奏する。In this way, the present invention prevents the shaft from being able to operate smoothly due to the contact between the pipe rack and the shaft pin, which are connected to the spring, and which creates a large resistance when the shaft rotates. Since the locking rod is less prone to bending, it is possible to prevent theft as well as damage to the steering lock device.
