備えられている。2. Description of the Related Art A driver bumps into a steering wheel when a vehicle crashes, and an axial impact load is applied to the steering column via the steering wheel. In order to absorb the impact on the steering column and ensure the driver's safety, the impact around the steering column is absorbed while the steering column is able to move in a smooth axial direction. A device is provided.

吸収機構を設けている。The steering column is generally supported and fixed to the vehicle body at two predetermined axial portions. Then, on the fixed part near the steering wheel, slide the steering column axially toward the front wheels to absorb the impact energy, and the impact that secures the safety when the driver hits the steering wheel by the reaction at the time of a collision. An absorption mechanism is provided.

ならない。Further, the rotatable fixed portion of the steering column closer to the front wheels is moved smoothly toward the front wheels by the operation of the shock absorbing mechanism of the fixed portion closer to the steering wheel. It has a structure that enables The fixed portion of the steering column near the front wheels must not only smoothly perform the sliding operation at the time of a collision but also always function as the tilt rotation center of the steering column in accordance with the tilt operation.

撃を吸収し、運転者を保護するものである。A conventional device of this type is disclosed, for example, in Japanese Utility Model Laid-Open No. 62-23771 as a tilt support structure for a tilt type steering device. This is because when a predetermined load acts in the axial direction of the steering column at the time of a collision, the support pin relatively moves in the slide hole portion, the steering column slides toward the front wheel side, and absorbs the impact at the time of the collision. It protects the driver.

な長孔を有するチルト機構のものが種々存在している。More specifically, at the time of a collision, when a predetermined load directed downward of the steering column is applied, the bracket moves along the elongated hole against the pressing force of the head of the support pin. . It is also disclosed that when the elongated hole of the bracket is made smaller than the diameter of the rotating hole and a predetermined load is applied, the edge of the elongated hole of the bracket moves while being crushed by the support pin. There are various tilt mechanisms having a long hole substantially similar to the above.

の安定した支持が困難である。In the above structure,
Since the elongated hole for absorbing impact energy is communicated with the pivot hole of the bracket for tilt adjustment in a notched state with the pivot hole, the outer peripheral side surface in the axial direction of the support pin is particularly formed at a location communicating with the oblong hole. Becomes a non-supported region, which reduces the support (contact) area, making it difficult to stably support the bracket by the support pin.

る。Further, the clearance of the support pin becomes extremely large in the communicating portion between the rotation hole and the long hole side with respect to the clearance between the diametrical direction of the support pin and the rotation hole, whereby the bracket moves. growing. Hence,
It causes backlash when rotating in tilt adjustment, and it is difficult to prevent this. It is also possible to suppress the movement in the diametrical direction by the friction holding force due to the axial tightening force of the support pin, but on the other hand, the resistance at the time of turning in the tilt adjustment becomes large, the movement becomes heavy, and the tilt adjustment becomes Interfere with. Further, if the width of the long hole is increased, the backlash is increased, and if the width is reduced, the backlash is reduced by that amount, but the energy absorption load in the direction of the long hole is increased and the sliding movement of the steering column becomes heavy.

できる。Further, in the communicating portion of the rotation hole and the long hole,
The support pin moves relative to the virtual position of the pivot hole in the communicating portion, beyond the virtual position to the starting end portion of the elongated hole. That is, the support pin, in the communication direction of the rotation hole and the long hole,
The amount of movement is larger than the clearance with the rotation hole. This distance is related to the size of the width, and by reducing the dimension of the elongated hole in the width direction in order to improve the relationship, the play width on the elongated hole side of the rotary hole can be reduced.

It is difficult to obtain a suitable load. Therefore,
As described above, the support pin and the width of the long hole of the bracket are set to the most convenient state, the rattling of the rotation support portion is suppressed during the tilt operation at the normal time, and the energy absorption load is set to a wide range as appropriate. It is extremely difficult to realize a mechanism that can be done with a simple structure. SUMMARY OF THE INVENTION It is an object of the present invention to suppress the rattling generated at the center of rotation in tilt steering as described above, to make the rotation operation stable and extremely smooth, and to improve the shock absorption operation at the time of a collision.
