Problems solved by technology

The steering lock mechanism includes a key lock collar embedded on the steering shaft and a steering lock device installed on the steering column outside the key lock collar. The groove of the key lock bush is fitted, thereby restricting the rotation of the steering shaft, so that it cannot be steered when the vehicle is stolen, etc.
[0003] In the conventional steering lock mechanism, if the steering wheel is turned with a large force while the steering is locked, the steering lock mechanism will be damaged and the locking function will be impaired.

no. 2 Embodiment approach

[0091] Next, while referring to Figure 8 as well as Figure 9A , Figure 9B A steering device according to a second embodiment of the present application will be described. The steering device according to the second embodiment differs from the steering device 1 according to the first embodiment only in the shape of the steering shaft and the shape of the slip ring, and the other configurations are the same as those of the first embodiment. Therefore, in the description of the second embodiment, only the shapes of the steering shaft and the slip ring will be described, and the description of other configurations will be omitted.

[0092] Figure 8 It is a figure which shows the cross section of the side surface of the steering shaft 20, the key lock boss|hub 21, and the slip ring 22 of the steering apparatus concerning 2nd Embodiment of this application.

[0093] In the second embodiment, a reduced-diameter portion 23 that is smaller in diameter than other adjacent portio...

no. 3 Embodiment approach

[0099] refer to Figure 10A , Figure 10B A third embodiment of the present application will be described. Figure 10A shows the side surface of the steering shaft 30 according to the third embodiment of the present application, Figure 10B The side surface of the steering shaft 30 according to the third embodiment of the present application, the slip ring 32 fitted on the steering shaft 30 and the cross section of the key lock boss 31 are shown.

[0100] The steering device according to the third embodiment of the present application differs from the steering device according to the first embodiment only in the shape of the steering shaft 30 , and the other configurations are the same as those of the first embodiment. Therefore, in the description of the third embodiment, only the shape of the steering shaft 30 will be described, and the description of other configurations will be omitted.

[0101] Such as Figure 10A As shown, in the steering shaft 30 according to the th...

Abstract

A steering apparatus includes a key lock collar (5) fitted on a steering shaft (2) and restricted from rotating by a steering lock mechanism when performing a steering lock, and a cylindrical slip ring (7) interposed between the steering shaft (2) and the key lock collar (5) in radial directions. The slip ring (7) includes a plurality of protruded portions (8) protruding outwardly or inwardly in the radial directions and being provided in a circumferential direction, and an axis-directional portion of the steering shaft (2) covered by the slip ring (7) is formed with a large-diameter portion (10a) and a small-diameter portion (10b), thereby further stabilizing slip torque of the key lock collar (5) and enlarging a range of a dimensional allowance.

Description

technical field [0001] The present invention relates to a steering device mounted on a vehicle or the like. Background technique [0002] Conventionally, there have been steering devices equipped with a steering lock mechanism that restricts rotation of a steering wheel in order to prevent a vehicle from being stolen. The steering lock mechanism includes a key lock collar embedded on the steering shaft and a steering lock device installed on the steering column outside the key lock collar. A groove or the like of the key lock bush is fitted to restrict the rotation of the steering shaft, making it impossible to steer the vehicle when the vehicle is stolen or the like. [0003] In the conventional steering lock mechanism, if the steering wheel is rotated with a large force while the steering is locked, the steering lock mechanism will be damaged and the locking function will be impaired. [0004] Therefore, there is a mechanism in which the key lock boss is rotated relative...
