Claims

[Scope of utility model registration request]

A steering column tube is attached to the vehicle body and has a harness insertion hole bored on one side of the axis of the flange formed at the upper end, and the steering column tube is housed in the steering column tube so as to be relatively rotatable.
A steering shaft having a pinion gear formed at its upper end; and a steering shaft that is attached to a flange of the steering column tube to house the pinion gear, is eccentric to one side with respect to the axis of the pinion gear, and has the harness insertion hole located on the inside. a gear housing having a substantially cylindrical circumferential wall that opens into the gear housing;
a rotational force transmission bearing mechanism that is fitted concentrically and transmits the rotation of the steering wheel to the pinion gear; and a rotational force transmission bearing mechanism that is arranged above the rotational force transmission member so as to be rotatable relative to the steering wheel; a center member that is locked to the vehicle body by a locking means disposed in a space between one side of the pinion gear and the rotational force transmission bearing mechanism; and a center member whose axial length is equal to the axial length of the peripheral wall. It has an approximately cylindrical shape that is shorter than that, and is arranged in a space between one side of the pinion gear and the rotational force transmission bearing mechanism, and its upper end is pressed by an elastic member compressed between it and the center member, and its lower end is pressed. a harness guide that is in pressure contact with the upper surface of the flange and connected to the harness insertion hole, and the rotational force transmission bearing mechanism has an internal gear that meshes with the pinion gear formed on the inner circumferential surface of the lower end, and A bearing inner ring to which the steering wheel is attached to a flange formed on an outer peripheral surface of an upper end, and a bearing outer ring fitted to an inner peripheral surface of a peripheral wall of the gear housing and rotatable relative to the bearing inner ring. A vehicle steering device characterized by:
