Claims

[Claims for Utility Model Registration] (1) A support bracket fixed to the vehicle body, a steering column having one end pivoted to the support bracket by a first horizontal shaft, and a first engaging tooth on one side. a first engaging member fixed to the lower surface of the steering column; one end pivotally supported on a second horizontal shaft provided on the support bracket; a second engaging member formed with a second engaging tooth that is removable from the engaging tooth of the support bracket, and a second engaging member provided between a portion fixed to the support bracket and the second engaging member; a spring that presses the engagement member in a direction to disengage the first engagement tooth and the second engagement tooth; a tilt lever pivotably supported on the support bracket; As the tilt lever swings, the second engaging member is engaged with and disengaged from the other side surface of the other end thereof, and when engaged, the second engaging member is pressed against the elasticity of the spring, and the second engagement member is pressed against the elasticity of the spring. A tilt type steering device comprising a pressing plate that engages one engaging tooth and a second engaging tooth. (2) A pivot bracket having first and second support walls that are parallel to each other is fixed to the lower surface of the support bracket, and a second horizontal axis is secured to the bottom surface of the support bracket, and the pivot bracket has first and second support walls that are parallel to each other. The tilt type steering device according to claim 1, further comprising: a compression spring provided between the first support wall and one surface of one end of the second engagement member. (3) The second support wall is extended from the first support wall to the other end of the second engagement member to form an extension, and the pressing plate is moved as the tilt lever swings. ,
3. The tilt type steering device according to claim 2, wherein the second engagement member can freely enter between the other side surface of the other end portion and the extension portion.
