In the example of FIG. 1A, the friction plate tilt long hole 322 and the tilt long hole 312 are substantially overlapped and are indicated by broken lines.

  As shown in FIGS. 1A and 3, pivot pins 4 and 4 are inserted into pivot insertion holes 311 and 311 formed on the front side of the fixed side portions 31 and 31, respectively. The pivot pins 4 and 4 are inserted into the long column pipe long holes 23 and 23 formed in the axial direction on the front side of the column pipe 2 and support the column pipe 2 from the width direction.

  With the above configuration, when the tightening bolt 52 is loosened by operating the tightening lever 6, the tightening of the friction plate 32, the hanger plate side plate 221, the fixed side portion 31, and the hanger bracket side plate 211 is released. The steering shaft 1 and the column pipe 2 can be tilted and telescopically adjusted. The column pipe 2, the hanger bracket 21, and the hanger plate 22 can telescopically move with respect to the fixed bracket 3, the pivot pin 4, and the fastening bolt 52, and can be tilted about the pivot pin 4.

  When the tightening bolt 6 is tightened by operating the tightening lever 6, the friction plate 32, the hanger plate side plate 221, the fixed side portion 31 and the hanger bracket side plate 211 are tightened in layers, and the steering shaft 1 and the column The pipe 2 is fixed to the vehicle body. The hanger plate 22 includes hanger plate side plates 221 and 221 and a hanger plate lower plate 222 formed with bent portions 222b and 222b on both sides in the width direction, and is formed in a substantially W shape.

  Therefore, when the tightening bolt 52 is tightened, the bent portions 222b and 222b are bent, and the interval between the hanger plate side plates 221 and 221 is narrowed. Since the hanger plate 22 does not stretch against the tightening of the tightening bolt 52 and does not hinder the tightening, the hanger plate 22 can come into surface contact with the fixed side portion 31, and an efficient and strong tightening holding force can be obtained. can do. Moreover, since the hanger plate 22 expands and contracts in the manufacturing process, it can be easily assembled between the friction plate 32 and the fixed side portion 31. In addition, when the tightening bolt 52 is released, the bent portions 222b and 222b are deflected to enable a smooth tilt / telescopic operation.

  As shown in FIGS. 1A and 2, the column pipe 2 supports a steering shaft 1, and a joint 11 is provided at the front end of the steering shaft 1. The pivot pin 4 as the tilt center axis is inserted into the column pipe long holes 23 and 23 formed at the axial center position of the column pipe 2, so that the position on the axis is substantially the same as that of the joint 11 which is a movable part at the time of tilt adjustment. The same speed can be maintained well.

  According to the first embodiment of the steering device of the present invention, the hanger plate 22 having the bent portions 222b and 222b and capable of expanding and contracting in the width direction is disposed between the fixed side portions 31 and 31 and the friction plates 32 and 32. When the driver operates the lever 6 and tightens the tightening bolt 52, the column pipe 2 and the steering shaft 1 can be firmly fixed. In addition, since the hanger plate 22 is fixed to the hanger bracket 21, the tightening holding force in the rotation direction can be improved without the hanger plate 22 rotating.

  Further, by loosening the tightening bolt 52 and releasing the tightening of the friction plate 32, the hanger plate side plate 221, the fixed side portion 31 and the hanger bracket side plate 211, the column pipe 2, the hanger bracket 21 and the steering shaft 1 are tilted. Adjustment and telescopic adjustment can be performed smoothly.

  The driver may get on and off the car by putting weight on the steering wheel. At this time, if the tightening holding force is low, the column pipe 2 and the steering shaft 1 rotate around the tightening bolt 52, and rattling may occur. More specifically, a force is applied to the front side of the vehicle body that is lowered downward and the rear side of the vehicle body is raised upward with the fastening bolt 52 as a center. Then, the column pipe 2 moves up and down by the gap between the pivot pin 4 and the column pipe long hole 23, and rattling occurs.

  Normally, the back of the pivot pin 4 has a loose structure such as a resin collar. However, the structure is complicated and the number of parts is large and the cost is high. In the present embodiment, the hanger plate 22 is fixed to the hanger bracket 21 so that the column pipe 2 can be prevented from rotating even when a force is applied in the vertical direction. As described above, the tightening holding force is strengthened, so that the pivot portion can have a simple structure. Further, the distance between the pivot pin 4 serving as the tilt center axis and the fastening bolt 52 can be shortened, the degree of freedom in layout is increased, and a compact steering device can be provided.

  In the embodiment, the fixed bracket 3 and the friction plate 32 are fixed to the vehicle body side. And the hanger bracket 21 and the hanger plate 22 are being fixed to the column pipe 2 side. In addition, since the fixing bracket 3, the hanger plate 22, the friction plate 32, and the hanger bracket 21 are sandwiched between each other and tightened with the tightening bolt 52, the column pipe 2 is efficiently moved to the vehicle body side. There is an effect that it can be firmly fixed.

  Furthermore, the hanger plate 22 can be incorporated into the gap between the friction plate 32 and the fixed side portion 31 without any resistance in the manufacturing process, but has a substantially bent shape with a convex bent portion 222b below, When pressed from the left and right by tightening, it is slightly shrunk and has the effect of being able to be firmly fixed.

  In addition, since the hanger plate fastening hole 222a is an elliptical fastening hole that is long in the width direction, even if the hanger plate lower plate 222 bends and shrinks slightly during fastening, the mounting bolt 24 moves freely to some extent in the width direction. The hanger bracket lower plate 212 and the hanger plate lower plate 222 are effectively prevented from being subjected to strain stress.

  A second embodiment of the steering device of the present invention will be described with reference to FIGS. 5 (A), 5 (B), 5 (C) and FIGS. On both hanger bracket side plates 211A and 211A of the hanger bracket 21A of the steering device, pivot side plates 213 and 213 are extended on the front side of the vehicle body (FIG. 6).
