〔引込み装置１の作動説明〕
（引戸２の開操作時）
図１１(A)に示されるように、引戸２が閉まり位置にある場合、スライダー１５が引戸中央側に位置され、このスライダー１５の基端側係合片１５ｃと先端側係合片１５ｅとの間の離隔部分に係合ピン１１が位置している。 [Description of operation of retractor 1]
(When opening sliding door 2)
As shown in FIG. 11A, when the sliding door 2 is in the closed position, the slider 15 is positioned on the center side of the sliding door, and the proximal end side engagement piece 15c and the distal end side engagement piece 15e of the slider 15 are located. The engaging pin 11 is located in the space part.

この閉まり状態にある引戸２の開操作を行うと、同図１１(B)に示されるように、係合ピン１１と先端側係合片１５ｅとの係合により、スライダー１５がスプリング部材１７の付勢力に抗して引戸端部側に移動するとともに、スライダー１５の先端側係合突部１４ｂが屈曲状案内溝１３ｂ側に案内されることによりスライダー１５を揺動させて仮停止状態とし、これに伴い先端側係合片１５ｅと係合ピン１１との係合が解除される。従って図１１(C)に示されるように、引戸２をさらに開操作できるようになる。   When the opening operation of the sliding door 2 in the closed state is performed, as shown in FIG. 11 (B), the slider 15 is moved to the spring member 17 by the engagement between the engagement pin 11 and the distal end side engagement piece 15e. While moving to the sliding door end side against the urging force, the leading end side engaging protrusion 14b of the slider 15 is guided to the bent guide groove 13b side, thereby swinging the slider 15 to a temporary stop state, Accordingly, the engagement between the distal end side engagement piece 15e and the engagement pin 11 is released. Therefore, as shown in FIG. 11C, the sliding door 2 can be further opened.

（引戸２の閉操作時）
次に引戸２の閉操作時の作動状態について説明する。引戸２を開き状態（図１１(C)）から図１１(B)に示される所定の位置まで閉操作を行うと、前記開操作によって仮停止状態とされたスライダー１５の基端側係合片１５ｃに係合ピン１１が衝突して、スライダー１５を揺動動作させ仮停止状態が解除される。これによりスライダー１５の基端側係合片１５ｃと先端側係合片１５ｅとの離隔部分に係合ピン１１が位置し、先端側係合片１５ｅと係合ピン１１とが係合した状態となる。その後、前記ピストン式ダンパー１６による制動力を受ながらスプリング部材１７の付勢力によって、引戸２が閉まり位置まで引き込まれるようになる（図１１(A)）。 (When sliding door 2 is closed)
Next, the operation state at the time of the closing operation of the sliding door 2 will be described. When the sliding door 2 is closed from the opened state (FIG. 11C) to the predetermined position shown in FIG. 11B, the proximal-side engaging piece of the slider 15 temporarily stopped by the opening operation. The engagement pin 11 collides with 15c, and the slider 15 is swung to release the temporarily stopped state. As a result, the engagement pin 11 is positioned at a separation portion between the proximal end side engagement piece 15c and the distal end side engagement piece 15e of the slider 15, and the distal end side engagement piece 15e and the engagement pin 11 are engaged. Become. Thereafter, the sliding door 2 is retracted to the closed position by the urging force of the spring member 17 while receiving the braking force by the piston type damper 16 (FIG. 11A).

ここで、前記スライダー１５の基端側係合片１５ｃが係合ピン１１に衝突した際、その反動で吊戸２の上端側を支点として下端側が回転するように上方向に跳ね上がることがあるが、前記跳上げ防止具２０の本体２１の上面がガイドレール４の天井面に近接し、前記隙間調整部材２２の下面が吊戸２の上面に近接するように配置されているため、前記係合ピン１１に衝突した際、前記ガイドレール４と吊戸２との間に存在する前記跳上げ防止具２０により吊戸２が跳上がるのを防止することができる。   Here, when the proximal end side engagement piece 15c of the slider 15 collides with the engagement pin 11, the reaction may cause the upper end side of the suspension door 2 to bulge upward so that the lower end side rotates about the fulcrum. Since the upper surface of the main body 21 of the flip-up preventing device 20 is disposed close to the ceiling surface of the guide rail 4 and the lower surface of the gap adjusting member 22 is disposed close to the upper surface of the suspension door 2, When it collides with the pin 11, it can prevent the suspension door 2 jumping up by the said jump prevention tool 20 which exists between the said guide rail 4 and the suspension door 2. As shown in FIG.

（スライダー１５が仮停止状態にない場合の引戸２の閉操作時）
図１２(A)に示されるように、スライダー１５が仮停止状態にない引戸２を建て込む場合や、引戸２の開操作時に何らかの理由でスライダー１５の仮停止状態が解除された場合など、スライダー１５が仮停止状態にない場合の引戸２の閉操作時の作動状態について説明する。この場合、図１２(B)に示されるように、先端側係合片１５ｅは、前記係合ピン１１を乗り越えることができるように該先端側係合片１５ｅの一部を弾性変形させ上端部がケース１２内に没入可能とされているため、引戸２を閉まり位置まで閉操作することにより、図１１(A)に示される通常の閉まり状態に復帰できる。その後、再度開操作を行うことにより、スライダー１５を仮停止状態にすることができる。 (When the sliding door 2 is closed when the slider 15 is not temporarily stopped)
As shown in FIG. 12 (A), when the slider 15 is built with the sliding door 2 not temporarily stopped, or when the slider 15 is temporarily released from the temporary stop state for some reason when the sliding door 2 is opened, the slider 15 The operation state at the time of closing operation of the sliding door 2 when 15 is not in the temporary stop state will be described. In this case, as shown in FIG. 12 (B), the distal end side engaging piece 15e is elastically deformed at a part of the distal end side engaging piece 15e so that it can get over the engaging pin 11. Can be immersed in the case 12, the normal closed state shown in FIG. 11A can be restored by closing the sliding door 2 to the closed position. Thereafter, by performing the opening operation again, the slider 15 can be temporarily stopped.
