Since the worm wheel, the drum, and the electromagnetic clutch are stacked in the axial direction, it is necessary to increase the size of the drive mechanism in the direction as a whole. In addition, since the transmission efficiency of the worm gear is low, the motor must be enlarged in order to obtain the required torque.

まず、切替ノブ70の操作により切替レバー56が電動切替位置Paに配置され、図6(a)に示されるように、係脱ブロック58によりリングギヤ46が回転不能に係止されている。このとき、駆動モータ22の回転は、第1小径ギヤ部41及び第1大径ギヤ部42d(交差軸歯車G1)を介して第1段の減速がなされて伝達ギヤ42に伝達される。伝達ギヤ42の回転は、第2小径ギヤ部42e及び第2大径ギヤ部48bを介して更に減速されてサンギヤ48に伝達される。サンギヤ48(第2大径ギヤ部48b)の回転は、遊星歯車機構G2において、サンギヤ48(サンギヤ部48a)を駆動軸とし、キャリア47を従動軸とし、リングギヤ46を固定軸とした減速比で第2段の減速がなされてドラム23に伝達される。従って、駆動モータ22の回転は、交差軸歯車G1、遊星歯車機構G2等を介して十分に減速されてドラム23に伝達される。
図9に示されるように、ECU81は、前記回転センサ82と電気的に接続されており、該回転センサ82の検出信号に基づいて前記ドラム23の回転位置及び回転速度等(即ちスライドドア20の開閉位置及び開閉速度等)を検出する。ECU81は、スライドドア20の開閉意思情報を取得するためのハンドルスイッチ84と電気的に接続されている。ECU81は、前記切替レバー56の回動位置(電動切替位置Pa又は手動切替位置Pm)を検出するための切替検出スイッチ85と電気的に接続されており、該切替検出スイッチ85の検出信号に基づいて切替レバー56の回動位置を検出する。ECU81は、前記駆動モータ22と電気的に接続されている。ECU81は、スライドドア20を全閉状態又は全開状態で保持するラッチ機構(図示略)を解放又は係合させるためのリリース・クローズアクチュエータ86と電気的に接続されている。ECU81は、ラッチ機構の作動に係るスライドドア20の保持情報を取得するためのラッチ・ポールスイッチ87と電気的に接続されている。なお、ラッチ機構は、スライドドア20に設置されたドアハンドル(図示略)とケーブル等の機械的連結部材(図示略)により機械的に連係されており、該ドアハンドルの操作によっても係合状態から解放可能である。ECU81は、これら回転センサ82等の検出結果に基づいて、駆動モータ22等を駆動制御する。
(1)本実施形態では、駆動モータ22の回転は、交差軸歯車G1、遊星歯車機構G2等を介して十分に減速されてドラム23に伝達される。この場合、減速に係る交差軸歯車G1、遊星歯車機構G2等の回転方向への伝達効率は、例えばウォームギヤにおける回転方向への伝達効率に比べて大きいことから、より小型のモータで必要なトルクを得ることができる。
図10に示されるように、左右対称のカム孔91aを有する切替レバー91を採用してもよい。係脱ブロック58によりリングギヤ46が係止されているとき、係合ピン58aはカム孔91aの周方向中央部に配置される。この場合、切替レバー91を付勢する復帰スプリング63(図5参照)は、係合ピン58aが周方向中央部に配置されるように切替レバー91を保持することが好ましい。また、この状態では、切替レバー91がいずれの方向に回転しても係脱ブロック58によるリングギヤ46の係止が解除可能であり、切替レバー91の手動切替位置Pmとして2つの位置が設定されてもよい。

切替部(切替レバー56等)を割愛して、基本的に電動のみでスライドドア20を開閉作動させるようにしてもよい。この場合、固定軸としてのリングギヤ46をハウジング31に回転不能に取着すればよい。また、スライドドア20の開閉位置は、駆動モータ22の回転軸22bの回転位置と相関するため、前記回転センサ82により回転軸22bの回転位置を検出するようにしてもよい。
