Claims

[Scope of utility model registration request]

A steering column tube attached to the vehicle body side, a steering shaft housed in the steering column tube so as to be relatively rotatable and having a pinion gear formed at its upper end, and a steering shaft attached to the upper end of the steering column tube to house the pinion gear. and a gear housing having a cylindrical peripheral wall eccentric to one side with respect to the axis of the pinion gear, and a gear housing rotatably and concentrically fitted to the peripheral wall of the gear housing,
a rotational force transmission bearing mechanism that transmits the rotation of the steering wheel to the pinion gear; and a rotational force transmission bearing mechanism disposed at a central position of the steering wheel so as to be rotatable relative to the steering wheel, and one side of the pinion gear and the rotational force transmission bearing mechanism. and a center member that is locked to the vehicle body side by a locking means arranged in a space between the rotational force transmission bearing mechanisms, and an internal gear that meshes with the pinion gear is formed on the inner peripheral surface of the lower end of the rotational force transmission bearing mechanism. an inner bearing ring to which the steering wheel is attached to a flange formed on an outer peripheral surface of the upper end; an outer bearing ring that is fitted to the inner peripheral surface of the peripheral wall of the gear housing and is rotatable relative to the inner bearing ring; A steering device for a vehicle, comprising: a cancel operation member provided at an upper end of the inner ring of the bearing and configured to cancel a lever switch disposed below the steering wheel from an on position.
