なすのがよい。The position and shape of the cutout groove 7b are such that while the stopper pin 8b is inserted, the cutout edge thereof is in contact with the stopper pin 8b.
It is preferable that it is suitable for engaging with the link 8 and restraining the rotation of the link 8.
ピン７ａと侵透孔８ａの係合を通じてリンク８をその一
端の２つの小歯車５と６の噛合方向（第１図反時計方向
）に回動付勢すべく操作用レバー７にトーションスプリ
ング９等を装着する。A torsion spring 9 is attached to the operating lever 7 in order to urge the link 8 to rotate in the direction in which the two small gears 5 and 6 at one end engage (counterclockwise in FIG. 1) through engagement between the pin 7a and the penetration hole 8a. etc. are installed.
なお、必要に応じて小歯車５及び６の支軸を両持ならし
めるべく軸３に補強板１０を固設してもよい。Note that, if necessary, a reinforcing plate 10 may be fixed to the shaft 3 so as to support the support shafts of the small gears 5 and 6 on both sides.
補強板１０に穿設される小歯車６のための駆送孔は、リ
ンク８の所要の回動を許容し得るのに適した形状となさ
しめるのがよい。It is preferable that the drive hole for the small gear 6 formed in the reinforcing plate 10 has a shape suitable for allowing the required rotation of the link 8.
第１図は、２つの小歯車５と６が噛合している状態を示
し、従ってシートの背凭れ部が一定の角度に固定されて
いる状態のりクライナーを示す。FIG. 1 shows the seat cliner in a state in which the two small gears 5 and 6 are in mesh, so that the backrest of the seat is fixed at a fixed angle.
本考案は上記の構成になるので、第１図に於いて、操作
用レバー７をスプリング９の付勢に抗して時計方向に回
動すると、リンク８が時計方向に回動し、小歯車５と６
の噛合が外れる。Since the present invention has the above-described configuration, in FIG. 1, when the operating lever 7 is rotated clockwise against the bias of the spring 9, the link 8 is rotated clockwise, and the small gear is rotated. 5 and 6
The mesh becomes disengaged.
上記の如く操作用レバー７は、バックプレート２上に軸
着されるためバックプレート２と一体的に軸３の回りに
回動し得、従って操作レバー７にそのまま操作力を加え
ておくことにより２つの小歯車５と６とは不噛合関係に
保たれるので、バックプレート２が軸３の回りに自在に
回動し得、両ヒンジプレートのなす角度を任意に変える
ことができる。As mentioned above, since the operating lever 7 is pivoted on the back plate 2, it can rotate around the shaft 3 integrally with the back plate 2. Therefore, by applying operating force to the operating lever 7, Since the two small gears 5 and 6 are maintained in a non-meshing relationship, the back plate 2 can freely rotate around the shaft 3, and the angle formed by both hinge plates can be arbitrarily changed.
操作用レバーから操作力を除くとスプリング９の付勢に
よってレバー７は反時計方向に回動し、従ってリンク８
は反時計方向に回動し、２つの小歯車５と６が噛合し、
両ヒンジプレートは一定の角度に固定される。When the operating force is removed from the operating lever, the lever 7 rotates counterclockwise due to the bias of the spring 9, and therefore the link 8
rotates counterclockwise, and the two small gears 5 and 6 mesh,
Both hinge plates are fixed at a fixed angle.
ところで、第１図に於いてバックプレート２に一直接に

５と６は対向して転がることはできないので、結局、２
つの小歯車５と６は互いにその進行を阻止し合い、従っ
てバックプレート２は軸３の回りに固定される。By the way, in FIG. 1, when the back plate 2 is directly inputted and rotated clockwise, the pinion 5 rolls clockwise on the arcuate rack 4 and rotates the pinion 6 counterclockwise. tries to do so, but since the two small gears 5 and 6 cannot roll facing each other on one rack 4, in the end, 2
The two pinions 5 and 6 prevent each other from advancing, so that the back plate 2 is fixed around the shaft 3.
これに反してバックプレート２に直接入力し、これを反

ので、スプリング９の付勢に抗してそれらの間の噛合が
外れ、バックプレート２の固定が解除されることがある
。On the other hand, when inputting directly to the back plate 2 and rotating it counterclockwise, the pinion 5 meshes with the arcuate rack 4 and rolls it counterclockwise, causing the pinion 6 to roll clockwise. Since an attempt is made to disengage the two small gears 5 and 6, the engagement between them may come off against the bias of the spring 9, and the fixation of the back plate 2 may be released.

ことなく保持される。As shown in FIG. 1, in the present invention, the stopper pin 8b installed on the link 8 fits into the notch groove 7b formed in the operating lever 7 when the two small gears 5 and 6 are engaged, and the stopper pin 8b engages with the notch edge to prevent rotation of the link 8, so the meshing of the two small gears 5 and 6 is maintained without being released.
上記の如く本考案はプレート回動阻止部材を要するもの

る。As mentioned above, the present invention requires a plate rotation preventing member, which acts directly on the back plate 2 and prevents the rotation of the plate.
The plate rotation preventing member is not limited to the above configuration as long as it prevents an input to disengage the two small gears 5 and 6 and keeps the back plate 2 fixed. The idea is as described above, so when fixing the back plate 2, the external force applied to it is distributed to two points: the point of meshing contact between the arcuate rack 4 and the small gear 5, and the point of meshing contact between the small gears 5 and 6. As a result, the breaking strength is substantially increased, and the gear ratio between the arcuate rack 4 and the small gear 5 can be used to adjust the minimum fluctuation angle of the back plate 2.
