大きな隙間が生ずることもある。 As part of this pad part non-rotation mechanism, the sun gear on the column side that is fixed to the column part, the sun gear on the pad side to which the pad part is fixed, and the two sun gears mesh simultaneously, so that the shafts are the same. There is a system based on a planetary gear mechanism consisting of a planetary gear, etc., but in the case of such a mechanism, it goes without saying that there is a backlash between the planetary gear and the sun gear, and there are also dimensional errors, assembly errors, etc. This may result in an even larger gap.

The planetary shaft 4 is attached so as not to move in the radial direction of the sun gears 3a, 3b via the
The column part 1 side of the planetary shaft 4 and the pad part 7
One planetary gear 5 is attached to each side, and two sun gears 5a and 5b, upper and lower, mesh with one planetary gear 5 at the same time to form one planetary gear 5. and 2 that meshes with it
The two sun gears form a set of gear configurations. This set of gears constitutes at least a part of the planetary gear mechanism.

太陽歯車３ａ，３ｂにはそれらが相互に反対方向
に回動しようとする回動・付勢力が働く。 When assembling a steering wheel configured in this way, it is sufficient to assemble it using a known procedure, but when the two gears, the upper and lower sun gears 3a and 3b, and the planetary gear 5 are engaged,
It is necessary to assemble the elastic member 6 by expanding and contracting or compressing it so that the two sun gears 3a and 3b are rotated and biased in mutually opposite directions. Therefore, a rotation/biasing force acts on the two sun gears 3a, 3b to cause them to rotate in opposite directions.
圧縮又は反発の程度は遊星歯車５の歯を太陽歯
車３ａ，３ｂの歯が接触した状態で挟んで、しか
も、遊星歯車機構が本来の機能をスムースに発揮
する程度とする。 The degree of compression or repulsion is such that the teeth of the planetary gear 5 are held in contact with the teeth of the sun gears 3a and 3b, and the planetary gear mechanism smoothly performs its original function.
以上のように構成された第一実施例について次
にその作用・効果を説明する。 Next, the functions and effects of the first embodiment configured as described above will be explained.

作を行なうと、ボスプレート１１の回動に伴つて
二つの遊星歯車５がコラム部７側とパツド部１側
のそれぞれの上下部太陽歯車３ａ，３ｂの周囲を
自転しながら公転する。 First, when the ring 13 is rotated to perform a steering operation, as the boss plate 11 is rotated, the two planetary gears 5 are connected to the upper and lower sun gears 3a and 3b on the column part 7 side and the pad part 1 side, respectively. It revolves around its surroundings.

対して常に不回動状態となる。従つて、パツド部
１側の下部太陽歯車３ｂに固着されているパツド
部１も不回動状態になる。 However, since the lower sun gear 3b on the column part 7 side is fixed to the column part 7, it cannot rotate, and the gear 3b and the upper sun gear 3a on the column part 7 side are connected via the elastic member 6. Therefore, the upper sun gear 3a does not rotate, and furthermore, the pad portion 1
The lower sun gear 3b on the side also does not rotate following the lower sun gear 3b on the column part 7 side, and is always in a non-rotating state with respect to the column part 7. Therefore, the pad portion 1 fixed to the lower sun gear 3b on the pad portion 1 side also becomes non-rotatable.

る。 Further, due to the elastic action of the elastic member 6, rotational and biasing forces in the circumferential direction that are different relative to each other are constantly applied to the upper and lower sun gears 3a and 3b on the column part 7 side and the pad part 1 side, respectively. Therefore, in the meshing portion between the planetary gear 5 and the two sun gears 3a and 3b, as shown in FIG.
The teeth 24c are sandwiched between the teeth 24a of the upper sun gear 3a and the teeth 24b of the lower sun gear 3b.
そのため、遊星歯車５の歯２４ｃと上部太陽歯
車３ａの歯２４ｂとの間に形成されるバツクラツ
シＢ及び遊星歯車機構の組み付け誤差等による隙
間が抑制されることになる。 Therefore, gaps caused by backlash B formed between the teeth 24c of the planetary gear 5 and the teeth 24b of the upper sun gear 3a and errors in assembly of the planetary gear mechanism are suppressed.
従つて、太陽歯車３ａ，３ｂと遊星歯車５との
間のガタツキが解消され、又、ステアリング操作
時の異音の発生が抑制される。 Therefore, rattling between the sun gears 3a, 3b and the planetary gears 5 is eliminated, and generation of abnormal noise during steering operation is suppressed.

ことはない。 Further, the planetary shaft 4 to which the planetary gear 5 is attached is connected to the sun gear 3 at the boss plate 11.
Since the gears a and 3b are fixed so as not to move in the radial direction, the planetary gears 5 and the sun gears 3a and 3b will not come out of mesh as in the prior art described above.
次に、第二実施例を第４図に基づいて説明す

うにしたものである。 In this embodiment, the upper sun gear 3a is provided on the lower sun gear 3b so as to be relatively rotatable about half a pitch, and furthermore, projecting pieces 17 and 18 are provided inwardly of both gears 3a and 3b on surfaces or surfaces on which they can be implanted. A depression 25 is provided. Elastic members 6 are attached to the projecting pieces 17 and 18 so that the upper and lower sun gears 3a and 3b are rotated and biased in different directions relative to each other.

Of course, it is possible to suppress gaps caused by assembly errors that occur when assembling the mechanism, eliminate rattling in the pads, and prevent abnormal noises from occurring when operating the steering wheel. Even when a rotational force is applied from the outside of the pad part, the engagement between the planetary gear and the sun gear does not come out of alignment, and when the engagement comes out, the planetary gear slips in the circumferential direction of the sun gear. , it is possible to reliably prevent the pad portion from rotating.
