Problems solved by technology

Therefore, it is necessary to provide the protrusion 15 on the large-diameter outer-diameter portion 16A of the inner column 1, and accordingly provide the guide groove 34 on the outer column 3 to keep the inner column 1 away from the fastening of the outer column 3. To maintain a stable structure, the cost becomes higher

Embodiment Construction

[0027] Embodiments of the present invention will be described below with reference to the drawings. In addition, in the present invention, the front-rear direction is set in the following description. In the state where the steering wheel device of the present invention is mounted on the automobile, the front-rear direction of the automobile is used as a reference, and the side corresponding to the front of the automobile is referred to as "front". side", and the side corresponding to the rear of the car is the "rear side". In addition, the direction connecting the front side and the rear side is called "axial direction". Also, the "width direction" refers to the left-right direction of the vehicle.

[0028] Such as figure 1 , image 3 As shown, the present invention is mainly composed of a fixed bracket 1, an inner column 2, an outer column A, a pivot bracket 4, a clamping member 6 and the like. First, the fixed bracket 1 is composed of fixed side portions 11 , 11 formed...

Abstract

A steering apparatus capable of preventing shape distortion of a bearing from an inner column due to tightening during tilt-and-telescopic adjustment and securing both telescopic travel of the inner column and tightening retention. The steering apparatus has a steering shaft 7, an inner column 2 that supports the steering shaft 7 via a bearing 81, an outer column A that embraces the inner column 2, a fixing bracket 1 that sandwiches the outer column A from both sides in a width direction, and a tightener 6 that tightens and releases the outer column A together with the fixing bracket 1. The inner column 2 has an embraced cylindrical section 21 that is embraced by the outer column A. A relief section 212 having an outer diameter that is formed smaller than other portions of the embraced cylindrical section 21 is formed in a middle region of the embraced cylindrical section 21 in an axial direction, and the bearing 81 that pivotally supports the steering shaft 7 is fixed to an inner circumferential side of the relief section 212.

Description

technical field [0001] The present invention relates to a steering wheel device provided with a tilt / telescopic adjustment mechanism capable of preventing the deformation of the shape of the inner column from the bearing to the bearing caused by clamping during the tilt / telescopic adjustment, and ensuring the amount of telescopic movement and clamping of the inner column. Retentivity. Background technique [0002] In recent years, there have been many so-called stub-type steering wheel devices in which the distance in the axial direction from the steering wheel to the upper universal joint is short. In such a stub-type steering wheel device, the length of the outer column in the axial direction is shortened, and the upper universal joint moves in the axial direction together with the inner column during telescopic adjustment. Patent Document 1 (Japanese Unexamined Patent Publication No. 2005-335491 ), which is a prior art, discloses a stub-type steering wheel device having ...
