詳細述されている。 FIG. 1 is an overall side view of the tail steering device A according to the present invention. In this figure, the lower main shaft (not shown, inside the column tube 12) of the upper main shaft 11 to which the steering wheel 10 is attached is shown. The tail steering device A, which adjusts the angle with respect to A rotational drive source B, a speed reduction mechanism C linked to this drive source B, and a spring coupler mechanism D that is activated by the rotation of the output shaft at the end of this speed reduction mechanism C and acts to transmit torque to the link 15. and an upper bracket 17 which is swung around a pin 16 via a link 15 by the coupler mechanism D. The detailed structure of the rotational drive source B, deceleration mechanism C, and spring coupler mechanism D is disclosed in the patent application filed by the applicant.
It is described in detail in No. 57-198344 (see Japanese Unexamined Patent Publication No. 59-89266).

が小さくなる方向にたわむことができる。 The rotary bearing 20 includes an engaging pin 21 fixed to the upper bracket 17, a collar 22 which is an intermediate member disposed on the outer periphery of the tapered shaft portion 21a of the engaging pin 21, and a collar 22 of the collar 22. An elastic member (made of rubber in this embodiment) 25 is in contact with the outer end surface and is pressed in the direction of the collar 22 by a nut 24 via a washer 23. The nut 24 is screwed into the male threaded portion 21b at the tip of the pin 21 and presses the elastic member 25 as described above. Further, a tapered hole 22a is formed in the axial center of the collar 22 in the axial direction thereof, and a slit 22b is provided. Therefore, when an external force is applied from the outer circumferential direction to the axial direction of the collar 22, the collar 22 can be deflected in a direction in which the diameter becomes smaller.

ある。 Further, a gap t1 always exists between the inner end surface of the collar 22 and one side surface of the attenuator bracket 17, and a gap t1 exists between the shoulder of the tapered shaft portion 21a and the washer 2.
The configuration is such that there is always a gap t2 between the two. Therefore, the collar 22 is attached to the elastic member 25.
It is always subjected to a pressing force by the taper and is constantly biased in the direction of taper contact. The male screw portion 21b, the nut 24, the washer 23, and the elastic member 25 constitute a biasing member. Note that the magnitude of the biasing force is such that the pin 21 can rotate smoothly.
次に本実施例の作用について述べる。 Next, the operation of this embodiment will be described.

テイルト角が得られる。 When you want to tilt the steering wheel 10 as indicated by the two-dot chain line 10' or 10'' in Figure 1, turning on a switch (not shown) activates the rotational drive source B, and the rotational force is It is transmitted to the spring coupler mechanism D via the deceleration mechanism C,
Link 15 moves at low speed in either direction of arrow a or b. Further, this movement is transmitted to the upper bracket 17, and the bracket 17 swings around the axis O (tail center) of the pin 16 to obtain a desired tail angle.

し摩滅量補完作用が生じる。 Here, relative rotation occurs between the engagement pin 21 fixed to the upper bracket 17 and the link 15 during the above-mentioned tilt action. However, since the above-mentioned biasing action by the biasing member occurs, no backlash occurs in the bearing portion. Further, even if the relative rotation portion is worn out due to long-term use, the biasing action causes the collar 22 to move slightly in the direction of contact with the taper, thereby producing a compensation effect for the amount of wear.

The rotation bearing 200 in this modification includes an engagement pin 210 fixed to the upper bracket 17, which is the first member, and a large diameter shaft portion 21 of the engagement pin 210.
It consists of a collar 220 which is an intermediate member disposed at the outer peripheral position of 0a, and an elastic member 25 which abuts the outer end surface of the collar 220 and is pressed in the direction of the collar 220 by a nut 24 via a washer 23.

してある。 This modified example differs from the above embodiment in that a tapered portion 220b is provided on the outer periphery of a collar 220 having a slit 220a, and the tapered portion 220b is brought into contact with the tapered hole 15a of the link 15, which is the second member, and the inclination direction of the taper is reversed. This is the point I made. However, the male screw part 210b at the tip of the engagement pin 21, the nut 24, and the washer 23
The biasing direction of the biasing member composed of the elastic member 25 and the elastic member 25 is the same as in the above embodiment. A gap t 3 always exists between the inner end surface of the collar 220 and one side of the attachment bracket 17, and a gap t 4 always exists between the shoulder of the large diameter shaft portion 210a of the pin 210 and the washer 23. The elastic member 25 is set to be thicker so that this occurs.
当該変形例の作用は上記実施例と同様であるか
