求項(1)の電動式チルトステアリング装置。[Scope of Claim for Utility Model Registration] (1) A fixed bracket that is fixed to the vehicle body and supports the lower steering shaft via the lower column, and an upper part that is swingably attached to the fixed bracket and connected to the lower steering shaft by a universal joint. An electric tilt steering device comprising a tilt bracket that supports a steering shaft via an upper column, a tilt electric motor attached to a fixed column side, and a conversion means that converts rotation of the electric motor into rocking of the tilt bracket, a screw shaft in which the conversion means is attached to the fixed bracket side and connected to the electric motor;
It is equipped with a screw nut that engages with the screw shaft, and an eccentric member that connects the screw nut and tilt bracket.A part of the screw nut is divided into two parts by a slit, and by tightening this part, the screw shaft can be screwed. The preload with the U-shaft is adjusted, and pins are integrally formed on both sides of the screw nut, and eccentric members are rotatably attached to these pins via spherical bushings, and the eccentric members are attached to the tilt bracket side. An electric tilt steering device characterized in that it is rotatably attached to. (2) The electric tilt steering device according to claim (1), wherein the eccentric member is attached to the tilt bracket side via a rolling bearing.
