Claims

[Scope of utility model registration request]

In a tilt type steering column, a tilt bracket is rotatably supported in a vertical direction on a clamp fixed to a vehicle body, and a steering shaft is connected to the tilt bracket by a universal joint passing through the tilt bracket and the clamp. One end of the lock plate is rotatably supported by a rod of a predetermined length, and lock grooves are formed in the width direction at regular intervals in the longitudinal direction on both opposing sides of the rod. a pair of links having lock pins that sandwich the other end of the lock plate and are removably engageable with the lock groove;
In addition, the lock pins are biased and pivoted so that they can approach each other, and a pair of cam holes are formed in the release lever, into which the lock pins are inserted and slid into sliding contact, and when the release lever is rotated, the pair of links are A tilt type steering column characterized in that the columns can be expanded in directions away from each other.
