The unit body 10A is configured to include an input shaft 21, an output shaft 22, a torque sensor 23, an electric motor 24, a worm gear 25, and a worm wheel 26.

電動舵取補助ユニット１０は、操舵軸４が接続具４Ａによって接続される入力軸２１の上端部を軸受３１により第１ハウジング１１に支持し（図３）、車輪側操舵部材５が接続具５Ａによって接続される出力軸２２の上下端部を上下の軸受３２Ａ、３２Ｂにより第２ハウジングと第３ハウジング１３に支持している（図３）。入力軸２１は接続具４Ａとの接続用セレーション２１Ａを上端外周部に備え、出力軸２２は接続具５Ａとの接続用セレーション２２Ａを下端外周部に備える。入力軸２１の中空部にはトーションバー２７が挿入され、トーションバー２７の一端は入力軸２１に連結ピン２７Ａで連結され、出力軸２２の中空部にはトーションバー２７の他端が挿入されてセレーション結合される。   In the electric steering assist unit 10, the upper end portion of the input shaft 21 to which the steering shaft 4 is connected by the connector 4A is supported by the first housing 11 by the bearing 31 (FIG. 3), and the wheel side steering member 5 is connected to the connector 5A.

The displacement in the rotational direction of the output shaft 22 causes the core 23C to be displaced in the axial direction, and the inductance of the detection coils 23A and 23B caused by the magnetic change around the detection coils 23A and 23B due to the displacement of the core 23C. Change. That is, when the core 23C moves toward the input shaft 21, the inductance of the detection coil 23A closer to the core 23C increases, and the inductance of the detection coil 23B farther away from the core 23C decreases. Torque can be detected.

電動モータ２４は、取付ボルト２８により第２ハウジング１２に取付け支持され、不図示のコントローラにより、トルクセンサ２３の検出トルクに応じて駆動される。電動モータ２４の回転軸には継手によりウォームギヤ２５が結合され、ウォームギヤ２５に噛合うウォームホイール２６を出力軸２２に固定してある。ウォームギヤ２５は、左右の軸受（不図示）により第２ハウジング１２に両端支持される。ウォームホイール２６は、第２ハウジング１２の内部で、出力軸２２における上側軸受３２Ａの直下にて該出力軸２２に固定される。   The electric motor 24 is mounted and supported on the second housing 12 by mounting bolts 28, and is driven by a controller (not shown) according to the torque detected by the torque sensor 23.

It is what was made to contact. The bearing 70 is formed of, for example, an angular ball bearing that can simultaneously apply a radial load and a thrust load of the steering shaft 4.

球面すべり軸受６０は、外輪６１を車体側ステー６の環状の支持部材６Ａの内周に圧入その他の手段により固定化される。軸受７０の外輪７１を球面すべり軸受６０の内輪６２の内周に挿入し、軸受７０の外輪７１の一端面を球面すべり軸受６０の内輪６２の内周段差部に突き当てる状態で、該内輪６２の内周に螺着されるナット８１により外輪７１の他端面を押圧し、このナット８１と該内輪６２の内周段差部との間に外輪７１を挟持して固定する。そして、操舵軸４を軸受７０の内輪７２に挿入し、操舵軸４の中間部に設けた鍔部ｆに内輪７２の一端面を突き当てる状態で、操舵軸４に螺着されるナット８２により内輪７２の他端面を押圧し、このナット８２と操舵軸４の鍔部ｆとの間に該内輪７２を挟持して固定する。   In the spherical plain bearing 60, the outer ring 61 is fixed to the inner circumference of the annular support member 6A of the vehicle body side stay 6 by press fitting or other means.
