Claims

[Scope of utility model registration request]

An upper steering shaft rotatably supported by the upper column and a lower steering shaft rotatably supported by the lower column are connected by a universal joint, and the upper column and lower column can be tilted around the joint. The tilt tightening/release bolt passes through the overlapping portion of the tilt bracket to which the lower column is attached and the distance bracket attached to the upper column, which is placed between the side plates of the tilt bracket, and the bolt is rotated. In a tilt column provided with a freely movable tilt operation lever, at least one of both side walls of the tilt bracket is formed with an elongated part that allows the tilt tightening/release bolt to be freely movable, and on both sides of the elongated part. The inner surface of the protrusion is formed into a tapered surface whose spacing becomes narrower as it goes inward, and the above-mentioned chill top tightening/
A wedge member having an outer surface having a tapered surface that engages with the tapered surface of the projection is attached to the release bolt, and the wedge member is pressed against the projection by rotating the tilt operation lever. Locking device in tocolumn.
