Steering apparatus

Abstract

The present invention provides a steering apparatus having simple construction, and good left and right balance of the clamping force, such that the clamping force does not fluctuate depending on the forward-backward position of the steering wheel 103. When fastening the tilt and telescopic function, by rotating an operation lever 349, the peak of a movable cam 344 runs over the peak of a stationary cam 343, which pushes the stationary cam 343 to the right side, and pulls a clamping rod 34 to the left side at the same time, so as to clamp side plates 32A, 32B. The inside surfaces 321A, 321B of the side plates 32A, 32B clamp flat surface section 61A, 62B of a distance bracket 6. The flat surface sections 62A, 62B elastically deform toward the inside in the width direction of the vehicle, and a pair of left and right clamping sections 66A, 66B of bent sections 64A, 64B clamp the outer circumferential surface of an inner column 2 from both the left and right sides.

Description

technical field [0001] The present invention relates to a steering device, in particular to a steering device with a telescoping function and a shock absorbing function, the telescoping function can adjust the position of the steering wheel in the front and rear direction, and the shock absorbing function can absorb the self-driver in a secondary collision. The shock load applied to the steering wheel can displace the steering wheel forward. Background technique [0002] In the steering device, in order to be able to adjust the position of the steering wheel in the front-rear direction, there is a steering device having a telescopic function in which the steering column is constituted by an outer column and an inner column slidably fitted in the axial direction. In addition, in a collision accident of a car, after the primary collision of the car colliding with other cars, etc., a secondary collision in which the driver collides with the steering wheel occurs, there is also ...

AI Technical Summary

Problems solved by technology

Therefore, there is a problem that even if the diameter of the outer column is reduced with a constant force using the expansion and contraction function, the force with which the outer column clamps the inner column still varies depending on the position of the steering wheel in the front-rear direction.

In the structure disclosed in Japanese Patent Application Laid-Open No. 5-262238, only one side of the outer circumference of the inner column is clamped by one pressing piece, so there is also a problem of poor left-right balance of the clamping force.

In addition, since the pressing piece, which is a part different from the spacer bracket, is slidably supported on the spacer bracket, there is also a problem that the structure is complicated and the manufacturing cost increases.
