本発明は車両の前後輪操舵装置、更に詳細には
ラツクピニオン式の前後輪操舵装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a front and rear wheel steering device for a vehicle, and more particularly to a rack and pinion type front and rear wheel steering device.
（従来の技術）

くラツクエンドブツシユ７が配設される。(Prior Art) A rack and pinion type front and rear wheel steering device generally has a rack shaft 4 connected to the steering system of one of the front and rear wheels and installed inside a steering gear box, as shown in a perspective view in FIG. an input pinion shaft 11 connected to the steering shaft and meshing with the input rack part 5 of the rack shaft 4; and an output pinion shaft 11 connected to the steering system of the other front and rear wheels and meshing with the output rack part 6 of the rack shaft 4. Equipped with a pinion shaft 21,
A rack end bushing 7 is disposed at the end of the rack shaft 4 for slidingly supporting the rack shaft 4.

た三つの箇所で夫々噛合、摺動が行なわれ、ラツ
ク軸の摺動上のこじりやピニオン軸の歯当りを防
止するための各摺動、噛合箇所での微調整が必要
となる。 Therefore, the rack shaft 4 of the front and rear wheel steering device engages and slides at three different locations, and the sliding and meshing operations are performed at three different locations to prevent prying on the sliding of the rack shaft and contact with the teeth of the pinion shaft. Minor adjustments will be required at certain points.

ドブツシユ７を動かすことにより行つていた。 Conventionally, the axis of the rack shaft 4 is determined by a first fulcrum consisting of the input pinion shaft 11 and the rack guide 52, and a second fulcrum consisting of the rack end bushing 7.
The tooth contact adjustment was performed by moving the rack end bushing 7 that constitutes the second fulcrum.

あつた。(Problem to be Solved by the Invention) However, in this adjustment method, since the adjustment is performed based on the tooth contact point of the input pinion shaft 11, the distance between the bush 7 and the output pinion shaft 21 is m, and the distance between the bush 7 and the input pinion shaft is m. When the distance between the axes 11 is l, the amount of adjustment required depending on the accuracy of the parts increases by l/m, and the amount of adjustment at the second fulcrum increases, causing the problem that adjustment becomes difficult depending on the accuracy of the parts. .

が作業者にわかりにくい欠点があつた。 In addition, the input pinion shaft 11 and the output pinion shaft 2
1. However, when adjusting the rotation by giving an eccentric amount to the rack end bushing 7 with the tooth contact point of the input pinion shaft 11 as a reference, the axis of the rack shaft 4 also moves in a circular motion. Therefore, when the amount of adjustment becomes large, the change in the pinion tooth contact becomes small with respect to the amount of screwing in of the adjustment bolt, which has the disadvantage that the adjustment point is difficult for the operator to understand.
