Problems solved by technology

Therefore, there is a possibility that the pipe string cannot be prevented from moving to the inclined upper side
[0010] However, the tilt lock mechanism disclosed in JP-A-2003-154944 does not have a sufficiently large tilt holding force
[0011] Also, in the tilt lock mechanism disclosed in JP-A-2006-312338, in order to enhance the tilt holding force, the number of parts increases and the manufacturing cost increases

Embodiment Construction

[0116] In the following embodiments, the present invention is applied to a tilt and telescopic type steering apparatus in which both the tilt position and the telescoping position of the steering wheel are adjusted. However, the present invention can be applied to a tilt type steering apparatus in which only the tilt position is adjusted.

[0117] figure 1 is an overall perspective view showing a state in which the steering apparatus of the present invention is installed in a vehicle. Such as figure 1 As shown, a hollow cylindrical column (column 1) is connected to the vehicle body. The steering shaft 3 is rotatably supported by the column 1 . A steering wheel 2 is connected to the right end (on the vehicle body rear side), and an intermediate shaft 5 is connected to the left end (on the vehicle body front side) of the steering shaft 3 via a universal joint 4 .

[0118] The intermediate shaft 5 includes a solid intermediate inner shaft 5a in which male splines are formed, ...

Abstract

A steering apparatus including an attaching bracket having a slot, respectively, a column supported on the attaching bracket, a fastening rod inserted into the slot and the column, an operation lever attached to the fastening rod, a cam mechanism converting an operating movement of the operation lever into an axial movement of the fastening rod, and a tilt lock mechanism including an eccentric cam rotating in accordance with the operation of the operation lever, an irregularity portion being formed on a cam face of the eccentric cam, and an irregularity portion formed on the cam face. When the operation lever is operated, the cam mechanism moves the fastening rod so as to fasten and clamp the column by the attaching bracket at a desired tilt position and the irregularity portion comes into contact with the attaching bracket so as to regulate an upward movement of the column.

Description

technical field [0001] The invention relates to a steering device. More specifically, the present invention relates to a steering apparatus capable of adjusting the tilt position of a column and collapsibly moving the column to the front side of the vehicle in the event of a secondary collision, so as to reduce the driver's shock. Background technique [0002] In a steering apparatus capable of adjusting a tilt position, a column is held by a vehicle attachment bracket so that the tilt position can be adjusted. After the inclination position has been adjusted, the joystick is operated and turned, and the slit for adjusting the inclination position formed on the connection bracket and the fastening rod inserted into the pipe string are fixed to each other so as to set the pipe string at a desired position Fastened and clamped to the connecting bracket. [0003] At the time of a secondary collision and an impact load is generated on the vehicle front side, when the driver c...
