A left-side side plate is integrally formed downward from an inner end of a left-side upper plate, and a right-side side plate is integrally formed downward from an inner end of a right-side upper plate. A front end of the left-side side plate and a front end of the right-side side plate are connected by a connection upper plate, and the left-side side plate, the connection upper plate, and the right-side side plate are formed continuously and integrally. A total length of the left-side upper plate and the right-side upper plate is formed shorter than a total length of the left-side side plate and the right-side side plate. The length totaling the left-side upper plate and the right-side upper plate is formed substantially equal to the length of the connection upper plate, and all of these members are press worked of a single metal plate.

A steering column may include a first adjustment drive for adjustments in a length adjustment direction and a second adjustment drive for adjustments in a height adjustment direction. The adjustment drives each have a drive motor. A joint control unit for the drive motors comprises three half bridges arranged in parallel and connected between two voltage potentials. Each half bridge has a high-side switch and a low-side switch connected in series via a connection point. The connection point of the first half bridge is electrically conductively connected to a first connection of a first drive motor. The connection point of a second half bridge is electrically conductively connected to a second connection of the first drive motor and to a first connection of the second drive motor. The connection point of a third half bridge is electrically conductively connected to a second connection of the second drive motor.

According to the present embodiments, a telescopic stroke is increased while an installation space of a steering column is easily secured, and a telescopic operation can be quickly performed without increasing a motor output. During the telescopic operation, noise may be reduced, and assemblability and mass productivity of the steering column may be improved.

A steering device includes an inner column, an outer column, a hanger bracket, and a fixing member. The hanger bracket has a guide hole which extends in the front-rear direction and through which the shaft portion of the fixing member passes. An edge portion of the guide hole of the hanger bracket is provided with a fixing portion and a gradually increasing resistance portion. The seat portion of the fixing member comes into contact with the fixing portion to fix the hanger bracket to the inner column. The gradually increasing resistance portion is disposed in front of the fixing portion and gradually increases frictional resistance between the fixing member and the hanger bracket according to forward displacement of the fixing member when the fixing member is displaced forward together with inner column by a secondary collision load being input to the steering shaft.

A steering column includes a steering shaft, a fixing bracket, a first cylinder, a second cylinder, an angle adjustment motor, an angle adjustment screw-nut assembly, a linkage assembly, a height adjustment motor, and a height adjustment screw-nut assembly, where the second cylinder is slidably sleeved with the first cylinder, the steering shaft runs through the first and second cylinders, the steering shaft includes an upper shaft and a lower shaft that are in splined connection, the upper shaft is supported in the second cylinder through a first bearing, the lower shaft is supported in the first cylinder through a second bearing, the first cylinder is hinged to the fixing bracket, the angle adjustment motor can drive the first cylinder to rotate relative to the fixing bracket, and the height adjustment motor can drive the second cylinder to axially move relative to the first cylinder.

An annular member includes a first through hole extending through a first face to a second face forming the back face relative to the first face and having an inner face formed as a concave curved face and a tubular spherical inner ring having an outer face formed as a convex curved face extending along the inner face of the first through hole. The spherical inner face is pivotable and tiltable along the inner face of the first through hole. In a lock mechanism, the annular member is supported to a steering support mount with a support portion being fixed to the spherical inner ring of the annular member provided at the one end and the other end is pivotally supported to a vehicle body frame and supports a tilt lever.
