Problems solved by technology

However, in the former structure, since the assembling direction of the anchor portion and the driven cam is limited, the assembling workability is reduced.
On the other hand, in the latter structure, not only an additional process of denting the outer surface of the support plate portion by flat pressing, but also a process of removing burrs associated with this process is required, and the manufacturing cost increases.

Embodiment Construction

[0052] Figure 1 to Figure 4 One example of the embodiment of the present invention is shown. In the configuration of this example, except for adjusting the steering wheel 1 (see Figure 5 ) In addition to the tilt mechanism for the up and down position, a telescopic mechanism for adjusting the front and rear positions is also installed. The tilting steering column device of this example is provided with: a steering column 6a with a tilting shaft 13 arranged at the front in the width direction (see Figure 5 ) as the center for swing displacement; displacement bracket 16a, which is fixedly arranged in the middle part of the steering column 6a in the axial direction; steering shaft 5, which is rotatably supported on the inner diameter side of steering column 6a, and The rear end part of the protruding rear end opening of the rear end fixes the steering wheel 1; the support bracket 14b is equipped with an upper plate part 34a and a pair of support plate parts 15b, 15c, and the a...

Abstract

The present invention provides a tilting steering column device having a configuration in which a displacement bracket (16a) is provided on the upper side of the steering column (6a), even when the steering wheel (1) is positioned in the adjustment range Even in the state of the upper end position, the operating force of the adjustment handle (24a) is suppressed from increasing. In the upper end portion of at least one of the long holes (17a) in the pair of long holes (17a, 17b) provided on the support plate portion (15b, 15c), a large width portion (33) is provided, and the large width portion (33) It has a width dimension larger than that of the anchor portion ( 25 ) or the upper half of the pressing member ( 29 ) in the front-rear direction.

Description

technical field [0001] The present invention relates to a tilt-type steering column device incorporated in a steering device for an automobile. Background technique [0002] Such as Figure 5 As shown, the steering device for an automobile is configured to transmit the rotation of the steering wheel 1 to the input shaft 3 of the steering gear unit 2 through the steering shaft 5, the free joint 7, the intermediate shaft 8, and the free joint 9. With the rotation of the input shaft 3, Push and pull left and right 1 pair of pull rods 4, give front wheel steering angle. The steering shaft 5 is rotatably supported by the steering column 6 supported on the vehicle body in a state where the cylindrical steering column 6 is penetrated in the axial direction. In addition, in the illustrated example, an electric power steering device is incorporated, and an electric motor 10 serving as an auxiliary power source is supported by a housing 11 fixed to the front end portion of the steeri...
