Since the arm portion 21 and the chair portion 23 can be configured compactly, the chair portion 23 can be easily moved in the vehicle interior (reference numeral 24 in FIG. 10).
Since the turning shaft 92 is configured compactly, the movable range of the indoor work auxiliary seat 20 in the vehicle interior can be widened.

図１１は自動車の室内作業補助シートの作用説明図（車室内から車室外への退出時）であり、車室内で作業を完了した作業者２２は、車室内２４で車両の開口部に背を向けて、車室内２４から車室外に後ろ向きに退出する。そして、係合部３６をアンロックし、図１０（ａ）の位置に戻り、昇降部２９を下降する。なお、作業者２２が椅子部２３から降りない場合など、作業の条件によっては昇降部２９を下降させないなど、操作を省略するなどの手順は、適宜変更が可能なものである。   FIG. 11 is a diagram for explaining the operation of the interior work auxiliary seat of the automobile (when leaving the vehicle interior to the exterior of the vehicle interior). Then, the vehicle exits backward from the passenger compartment 24 to the outside of the passenger compartment. And the engaging part 36 is unlocked, it returns to the position of Fig.10 (a), and the raising / lowering part 29 is lowered | hung. Note that, for example, when the operator 22 does not get off the chair portion 23, the procedure such as omitting the operation such as not lowering the elevating portion 29 depending on the work conditions can be changed as appropriate.

退出時において、椅子揺動機構１２４を設けたので、作業者２２が椅子部２３を後傾させることで、作業者２２の体が車両１３の一部に干渉し難くなり、車両１３からの退出を一層容易に行うことができる。関節部３４でアーム部２１を折り曲げ、足などで車両１３の床などを押すことにより、車室内２４から車室外に椅子部２３を容易に退出させることができる。   Since the chair swinging mechanism 124 is provided at the time of leaving, the operator 22 makes it difficult for the body of the operator 22 to interfere with a part of the vehicle 13 by tilting the chair portion 23 backward. Can be performed more easily. The arm portion 21 is bent by the joint portion 34 and the floor of the vehicle 13 is pushed by a foot or the like, whereby the chair portion 23 can be easily withdrawn from the vehicle interior 24 to the outside of the vehicle interior.

図２に戻って、第２アーム部３２の先端部３２ａと椅子部２３間に、椅子部２３を旋回可能に支持する椅子旋回機構１２１と椅子部２３を水平軸周りに揺動可能に支持する椅子揺動機構１２４とを備えた。椅子旋回機構１２１及び椅子揺動機構１２４は、アーム部２１の先端２１ａより先に配置される椅子部２３の質量を支持すれば良いため、これらの機構１２１、１２４がアーム部２１の根元である後端２１ｂに配置される場合に較べて、これら２つの機構１２１、１２４に要求される剛性は小さくても良い。従って、椅子旋回機構１２１及び椅子揺動機構１２４を軽量且つコンパクトな構造とすることができる。   Returning to FIG. 2, between the distal end portion 32 a of the second arm portion 32 and the chair portion 23, the chair turning mechanism 121 that supports the chair portion 23 so as to be turnable and the chair portion 23 are supported so as to be swingable around a horizontal axis. And a chair swinging mechanism 124. Since the chair turning mechanism 121 and the chair swinging mechanism 124 only need to support the mass of the chair portion 23 arranged before the tip 21 a of the arm portion 21, these mechanisms 121 and 124 are the base of the arm portion 21. Compared with the case where it is arranged at the rear end 21b, the rigidity required for these two mechanisms 121 and 124 may be small. Therefore, the chair turning mechanism 121 and the chair swinging mechanism 124 can have a lightweight and compact structure.

回動支持部２８は、車両１３の搬送ハンガー１２と係合する係合部３６を備え、車両１３の搬送手段１７である搬送ハンガー１２の移動に同期して移動するようにした。

Further, the rotation support portion 28 is detachable from the conveying means 17 so as to move in synchronization with the movement of the workpiece W conveyed in a predetermined direction.

作業開始前に係合部を搬送ハンガー１２と係合させ、作業完了後に係合部を搬送ハンガー１２との係合を解除することで、１台の自動車の室内作業補助シート２０を使い回しすることが可能となる。従って、装置費用を低減することができる。   Engage the engaging part with the transport hanger 12 before starting the work, and release the engagement of the engaging part with the transport hanger 12 after the work is completed, thereby reusing the indoor work auxiliary seat 20 of one automobile. It becomes possible. Therefore, the apparatus cost can be reduced.

回動支持部２８は、支持部材１０としての基盤Ｂに対し車輪１５、１５により移動可能に設けられているので、回動支持部２８の移動に必要な力を減らすことができる。回動支持部２８の移動に必要な力が減るので、回動支持部２８の移動を円滑に行わせることができる。   Since the rotation support part 28 is provided so as to be movable by the wheels 15, 15 with respect to the base B as the support member 10, it is possible to reduce the force necessary for the movement of the rotation support part 28. Since the force required for the movement of the rotation support portion 28 is reduced, the rotation support portion 28 can be moved smoothly.

図１２は図７の別実施例図である。
