Claims

[Claims for Utility Model Registration] (1) An electric tilt steering drive device that moves the steering wheel position upward or downward by rotating a tilt motor in the forward or reverse direction by operating a vertical direction operation switch. As the vertical operation switch, a rotation detection switch is used that detects horizontal rotation within the range of play of the steering wheel and issues a vertical movement signal, and the steering wheel position is determined by the vertical movement signal of the rotation detection switch. 1. A tilt steering device for a vehicle, wherein upward or downward movement is performed by ANDing a vehicle speed zero signal from a vehicle speed sensor and an ON signal of an electric tilt steering drive device. (2) The rotation detection switch is fitted into a groove provided on the outer periphery of the steering shaft with a frictional force so as to be able to slip when a torque exceeding a predetermined value is applied. a guide ring having a circumferential slit with a length corresponding to the play in the moving direction; a stop pin fixed to the steering column and loosely fitted into the slit of the guide ring; Utility model registration claim 1 consisting of two photo interrupters that are respectively attached to both sides and emit a signal using the other end of the slit as an optical path when the stop pin is located near one end of the slit.
The tilt steering device for a vehicle as described in 2.
