Problems solved by technology

However, the structure described in Patent Document 6 is more complicated than the structure described in Patent Document 5, and the height dimension of the steering column device is higher.
Furthermore, when a force in a direction in which the steering column is tilted is applied in a secondary collision, the same problem as that of the structure described in Patent Document 5 occurs.

Embodiment Construction

[0055] The first example of embodiment

[0056] Figure 1 to Figure 10 The first example of the embodiment of the present invention is shown. Among them, including this example, the feature of the present invention lies in a structure for supporting the outer column 11a constituting the steering column 6a on the vehicle body in a state in which a forward impact caused at the time of a secondary collision Under the action of the load, the outer column 11a can be displaced forward relative to the vehicle body, and can prevent downward descent after the forward displacement. The structure, function and utilization of other parts of the steering device Figure 18 ~ Figure 20 The conventional configurations described are the same, so the same reference numerals are assigned to equivalent parts, and overlapping descriptions are omitted or simplified. Hereinafter, the description will focus on the characteristic parts of this example.

Abstract

Disclosed is a structure which does not lead to increased height, which prevents a steering column (6a) from falling even if during second impact the steering column (6a) is displaced in the forward direction, and which, notwithstanding, ensures the function which allows smooth displacement of the steering column (6a) in the forward direction during second impact. The disclosed steering column support device is provided with a non-falling side bracket (45) fixed to the vehicle body, and a pair of bolts (47), a pair of support capsules (16a), and a falling side bracket (46) supported by the steering column (6a). During second impact, the supporting force of the support capsules (16a) against the non-falling side bracket (45) is lost, and the steering column (6a) is displaced in the forward direction along with the bolts (47) and support capsules (16a) and the falling side bracket (46), but the steering column (6a) does not fall off the non-falling side bracket (45).

Description

technical field [0001] The present invention relates to an improvement of a steering column support device that supports a steering column on a vehicle body and that constitutes a steering device for imparting a steering angle to steered wheels of a vehicle. Background technique [0002] A steering device for a vehicle is a device for arbitrarily changing the direction of travel of the vehicle, for example, as Figure 18 As shown, the steering device of the automobile has the following structure: the rotation of the steering wheel 1 is transmitted to the input shaft 3 of the steering gear mechanism 2, and a pair of left and right steering tie rods 4 are pushed and pulled along with the rotation of the input shaft 3, and the front wheels are given steering angle. The steering wheel 1 is supported and fixed to a rear end portion of a steering shaft 5 , and the steering shaft 5 is rotatably supported by the steering column 6 in a state of being inserted in the axial direction t...
