等の問題点を有するものであった。[Problems to be Solved by the Invention] However, in the conventional slow rotation shaft device, the shaft body 31 and the cap member 33 constituting the shaft body 3 are assembled so that they can rotate freely relative to each other. Initial torque cannot be applied at the time of sub-assembly of the shaft body 3, and must be applied only in relation to the rotating member 1 and the fixed member 2, which are the mating members, when the shaft body 3 is attached to the pivot portion of the rotating member 1. (2) Although the torsion bar 4 is limited in its twisting direction during use due to its settings, it is possible for the torsion bar 4 to become sagging due to malfunction of the cap member 33 in the opposite direction. (1) Since there is no means for regulating the rotation angle in the shaft body 3 itself, the torsion bar 4 will become sagging when rotated beyond the maximum rotation angle. It is necessary to provide a means, and processing of both members 1 and 2 becomes troublesome;

動範囲を規制するストッパー等の加工が不要となる。Therefore, it is not necessary to process the rotating member 1 and the fixed member 2 with a stopper or the like to restrict the rotation range of the rotating member 1.
また、トーションバー４に初期トルクを付与するには次
のようにする。Further, to apply initial torque to the torsion bar 4, do as follows.
軸本体３１にキャップ部材３２及び３３を組付ける際、
トーションバー４の一端フツク部４１を軸本体３１の貫

突起３９ａと衝合しない軌道になるように配置させる。When assembling the cap members 32 and 33 to the shaft body 31,
One end hook portion 41 of the torsion bar 4 is engaged with the through hole 34 of the shaft body 31, and the other end hook portion 42 is engaged with the recess 36 of the cap member 33. At this time, the cap member 3
3 is arranged so that the engaging protrusion 39b is on a trajectory that does not abut against the engaging protrusion 39a of the shaft body 31 when rotated.

とが相互に逆方向へ回転付勢されるが、係合突起３９ａ
と３９ｂの衝合により上記方向の回転が規制されトーシ
ョンバー４に初期トルクを付与することができる。Then, the cap member 33 is rotated with respect to the shaft body 31 to twist the torsion bar 4, and while maintaining this twisted state, the cap member 33 is inserted onto the small diameter shaft portion 31b, and the annular groove 33a is fitted into the annular rib 31c. let When the cap member 33 is assembled to the shaft body 31 in this way, the torque of the torsion bar 4 causes the shaft body 31 and the cap member 33 to
are urged to rotate in mutually opposite directions, but the engaging protrusion 39a
Rotation in the above direction is restricted by the collision between the torsion bar 4 and the torsion bar 4, and initial torque can be applied to the torsion bar 4.
このように軸体３は軸体のサブアッセンブリ時にトーシ
ョンバー４に初期トルクを付与することができる。In this way, the shaft 3 can apply an initial torque to the torsion bar 4 during subassembly of the shaft.
このように軸体３は回転部材１の枢支部に単に軸挿させ

ことができる。このため本発明に係る緩動回転軸装置は
組立てが容易である。In this way, by simply inserting the shaft body 3 into the pivot portion of the rotating member 1, a slow rotation shaft device to which an initial torque is applied can be obtained. Therefore, the slow rotation shaft device according to the present invention is easy to assemble.
［発明の効果］
以上述べたように、本発明は、軸体を構成する軸本体と
キャップ部材とに、これら２部材の相互回転を規制する
係合突起を設けたので、誤作動あるいは最大回転角度以

回転軸装置を得ることができる。[Effects of the Invention] As described above, in the present invention, the shaft body and the cap member constituting the shaft body are provided with an engaging protrusion that restricts mutual rotation of these two members, so that malfunction or maximum rotation can occur. It is possible to reliably prevent the torsion bar from sagging caused by rotation beyond an angle, and to obtain a slow rotation rotating shaft device that operates stably over a long period of time.

枢支部に単に軸挿するだけで、初期トルクが付与された
緩動回転軸装置を得ることができ、組立てが極めて容易
である。In addition, since the shaft itself can be given initial torque during its subassembly, the slow-rotating rotating shaft device can be given initial torque by simply inserting the shaft into the pivot of the rotating member. It is extremely easy to assemble.
