A steering device including a steering column supporting a steering shaft to be coupled to a steering wheel. The steering column is sandwiched between a bracket including a first support plate and a second support plate with a tightening shaft penetrating the first support plate and the second support plate and including a male thread at an end of the tightening shaft on a side close to the second support plate having a nut attached thereon. An operation lever is disposed between the nut and the second support plate and penetrated by the tightening shaft. A case including a bottom surface facing an end surface of the tightening shaft is attached to the operation lever, and a coil spring coming into contact with the bottom surface and the tightening shaft.

Steering device

A steering apparatus () of the invention of the present application is disclosed, which includes an electrifying plate () secured to an inner column () and received within a guide groove () of an outer column (). The electrifying plate contacts an electrifying cover () of the outer column, and configures part of an electrifying path leading to the outer column from the inner column. The invention of the present application enables a new electrifying path to be ensured, which extends from a steering wheel () to a car body ().

Steering apparatus

A steering device includes: an inner column having a first hole opened therein; an outer column having a slit; an outer column bracket clamping the outer column along with a telescopic friction plate; a rod supporting the telescopic friction plate; an inner column bracket supported by the telescopic friction plate and having a second hole opened therein; a shear pin separably connecting the inner column and the inner column bracket to each other at a position across the first hole and the second hole; and a rotation stopper provided at a rear side in relation to the rod and contacting the telescopic friction plate when the telescopic friction plate rotates about the rod in the event of a secondary collision.

A steering apparatus is disclosed, which includes a steering shaft (), an outer column (), an inner column () fitted in the outer column, a guide member () received in a guide groove () formed in the outer column and fitted to the inner column (), and an electrifying member () fitted to the inner column inwardly of the guide groove and getting in contact with the outer column ().

A steering apparatus has a guide member () being received in a guide groove () and attached to an inner column (), metal fittings that have conductivity, is in contact with the inner column to attach the guide member to the inner column, and an electricity-carrying plate () that is composed of a metal plate material having conductivity, is fixed to the inner column in contact with the metal fittings, and elastically deforms and in contact with an inside of a pair of guide walls at a predetermined contact pressure, so that a new electricity-carrying passage from a steering wheel to a vehicle body is secured.

A steering apparatus () is disclosed, which includes: a steering shaft () having a conductive property and transferring a steering force; an outer column () having a conductive property and supporting the steering shaft () rotatably; an inner column () having a conductive property, being fitted in the outer column () to enable a relative movement in an axial direction supporting the steering shaft () rotatably together with the outer column (); a bracket () having a conductive property, retaining the outer column () and being fixed to a vehicle body; and an electrifying lead () having a conductive property and configuring a part of an electrifying path leading to the vehicle body from the inner column ().

A steering device includes an inner column, an outer column, an outer column bracket, an inner column bracket, a shear pin, and a damper. A first hole is formed in the inner column. The outer column has a slit formed by notching one end. The outer column bracket tightens the outer column together with a telescopic friction plate. The inner column bracket is supported by the telescopic friction plate, and has a second hole. The shear pin detachably connects the inner column and the inner column bracket to each other at a position across the first hole and the second hole. The damper faces an internal end portion wall of the slit in an axial direction of the inner column.

A steering device which contracts by an impulse load. The steering device includes a cylindrical inner column having a first hole opened therein, an outer column having a cylindrical shape into which at least a part of the inner column is inserted and having a slit at one insertion side end of the inner column, an outer column bracket fixed to a vehicle body side member to support the outer column and to tighten the outer column along with a telescopic friction plate, an inner column bracket having a second hole opened therein and supported by the telescopic friction plate, and a shear pin provided at a position straddling the first hole and the second hole and detachably connecting the inner column and the inner column bracket to each other.
