Problems solved by technology

[0021] However, such a conventional structure has the following problems: the assembly structure of the first friction plate 31 and the second friction plate 32 is complicated, and the manufacturing cost is high.
However, for configurations with interference sleeves and Figure 51 and Figure 52 The combination of the structures shown that use multiple friction plates to improve the position retention of the steering wheel 1 is not suggested
Although these structures can be independently attached to the telescopic steering device, the assembly work is cumbersome and the cost cannot be avoided

no. 1 Embodiment approach

[0161] [Ninth example of the first embodiment]

[0162] Figure 18 and Figure 19 A ninth example of the first embodiment of the present invention is shown. The outer column 42h constituting the steering column device of this example has the same basic structure as the outer column 42a of the second example of the first embodiment. In this example, the support portion 46a of the outer column 42h is composed of a front support portion 60 and a rear support portion 61 . The front side support portion 60 and the rear side support portion 61 are provided at the same position as the structure of the eighth example of the first embodiment, and the axial dimension of the radially overlapping portion of the outer column 42h and the inner column 43 is the shortest. Both the front side support portion 60 and the rear side support portion 61 can contact the outer peripheral surface of the inner column 43 . In addition, this example can be implemented in combination with the examples ...

Abstract

[Problem] To obtain a configuration enabling an inner column (43) to be stably held on the inner diameter side of an outer column (42). [Solution] The outer column (42) together with support sections (46) is formed by bulging radially outward a hollow pipe by hydroforming. A displacement-side bracket (34) is formed integrally with the outer column (42) also by bulging. Protrusions (47a, 47b) forming the support sections (46) are formed at three or more places in the circumferential direction on the inner peripheral surface of the outer column (42). Thus, the protrusions (47a, 47b) and the outer peripheral surface of the inner column (43) are made to be in contact with each other at three or more places in the circumferential direction.

Description

technical field [0001] The present invention relates to a steering column device applied to a telescopic steering device having a telescopic function for adjusting the front and rear positions of a steering wheel. Background technique [0002] Such as Figure 46 As shown, the steering device for a motor vehicle is configured in such a way that the rotation of the steering wheel 1 is transmitted to the input shaft 3 of the steering gear unit 2, and as the input shaft 3 rotates, a pair of left and right steering tie rods 4 are pushed and pulled, thereby giving the front wheels a certain amount of rotation. the 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 penetrating in the axial direction through a cylindrical steering column 6 . The front end of the steering shaft 5 is connected to the rear end of an intermediate shaft 8 via a unive...
