Claims

[Claims for Utility Model Registration] (1) A tilt adjustment lever that allows the height position of the steering wheel to be adjusted freely as the steering wheel swings;
In a tilt-type steering device with a flip-up mechanism, which includes a flip-up lever that allows the steering wheel to be flipped up beyond the tilt adjustment range when the steering wheel is engaged, A limiting mechanism is provided to limit the amount of rise within a tilt adjustment range, and the limiting mechanism is engaged only between the limiting mechanism and the flip-up lever as the flip-up lever swings. A tilt-type steering device with a flip-up mechanism characterized by being provided with a release mechanism. (2) A first steering column into which a first steering shaft is inserted, which fixes a steering wheel at one end, and one end of which is inserted into the other end of this first steering column, and the first horizontal axis is centered on the first steering column. a second steering column that is swingably coupled and has a second steering shaft inserted therein; a spring for flipping up one end of the first steering column; and the first horizontal shaft. a universal joint that is on an extension of the first steering shaft and that connects the other end of the first steering shaft and the second steering shaft; and a universal joint that is fixed to the lower surface of the first steering column and that connects the horizontal axis A fixed gear having first meshing teeth formed on a central arc-shaped convex surface, and a second horizontal shaft provided on a support bracket fixed to the vehicle body and to which one end of the second steering column is fixed. a movable gear having an end pivotally supported and a second meshing tooth formed on the upper edge of the front end that meshes with the first meshing tooth; a base end loosely engaged with the second horizontal shaft; A memory gear having a third meshing tooth formed on its upper edge that meshes with the first meshing tooth, and a memory gear that swings about the first horizontal axis,
a tilt adjustment lever that disengages the second and third meshing teeth from the first meshing teeth; In the tilt type steering device with a flip-up mechanism, which includes a flip-up lever that disengages from the first meshing tooth, the flip-up lever is provided between the first steering column and the support bracket when engaged. A limiting mechanism is provided to limit the amount by which the first steering column is flipped up by the spring for adjusting the tilt, and the swinging of the flip-up lever is limited only between this limiting mechanism and the flip-up lever. 1. A tilt-type steering device with a flip-up mechanism, characterized in that a release mechanism is provided for releasing the engagement of the limiting mechanism when the above-mentioned restriction mechanism is released. (3) The restriction mechanism includes a protrusion protruding from the side surface of the fixed gear, a proximal end pivoted to a horizontal shaft provided on the support bracket, and a hook at the distal end that can be freely engaged with and detached from the protrusion. The release mechanism is a pressing piece that is fixed to a part of the flip-up lever and swings the lock lever as the flip-up lever swings. A tilt-type steering device with a flip-up mechanism according to claim 2.
