Claims

[Claims for Utility Model Registration] (1) A support bracket fixed to the vehicle body, an upper column whose one end is pivoted to the support bracket by a horizontal shaft, and the upper column or the upper column supported by the upper column. A first engaging part provided on a part of the member supported by the supporting bracket, and a second engaging part provided in a part of the supporting bracket or a member supported by the supporting bracket, In a tilt type steering device comprising a tilt lever for engaging and disengaging the first engaging part and the second engaging part, a part thereof has a fixed side hook part and is fixed to the support bracket. One end of the fixed bracket is fixed to a part fixed to the fixed bracket, and the other end is fixed to a part fixed to the upper column, respectively, and by displacing the upper column to the uppermost position, the fixed bracket is fixed to the fixed bracket. a flexible tensioning member having a length sufficient to tension between the fixed part and the part fixed to the upper column; and a part of the flexible tensioning member that can freely engage with the fixed side hook, Each has a pressing portion in a portion facing the flexible tension member, a displacement bracket that is rotatably and slightly displaceably locked to the fixed bracket, and a displacement bracket that is fixed to the upper part when a strong force is applied. One end thereof is attached to a fixed part of the lower column that is displaced in the axial direction toward the column, and the other end is attached to a part of the displacement bracket.
and a pressing rod coupled to each other, and as the pressing rod presses a part of the displacement bracket based on the displacement of the lower column, the fixed side hook portion and the displacement side hook portion are engaged. At the same time, the pressing part presses the middle part of the flexible tensioning member in a direction perpendicular to the length direction of the flexible tensioning member, so that the flexible tensioning member A tilt type steering device characterized by tensioning a tension member. (2) A support bracket fixed to the vehicle body, an upper column whose one end is pivotally supported by the support bracket by a horizontal shaft, and a support bracket provided on the upper column or a part of the member supported by the upper column. a second engaging portion provided on the support bracket or a part of the member supported by the support bracket; In a tilt type steering device comprising a tilt lever that engages and disengages from a second engaging portion, the steering device includes a longitudinally long elongated hole formed in a part of the support bracket, and a tilt lever that is freely displaceable along the elongated hole. a slider; an extension portion provided on a portion of the upper column facing a position near one end of the elongated hole; a tension cable having one end coupled to the slider and the other end coupled to the lower column that is displaced in the axial direction toward the upper column when a strong force is applied; , as the tension force by which the tension cable pulls the slider is released based on the displacement of the lower column, the slider is moved to one end of the elongated hole by the elasticity of the spring; A tilt type steering device characterized in that the slider and the extension portion can freely collide with each other.
