Abstract

　入力側から一定の回転方向をもった駆動力を負荷側に出力する際に、正回転と逆回転を適宜切り替え、かつ増減速させて出力できるようにすることである。 　入力歯車１２と出力歯車１３との間に切替機構１４が設けられる。前記切替機構１４は、遊星歯車機構１６、制御歯車１７及びばねクラッチ１８によって構成される。前記遊星歯車機構１６は、内歯歯車２３と太陽歯車２１の間に介在された遊星歯車２４及び該遊星歯車２４を支持するキャリヤ２６によって構成される。内歯歯車２３と入力歯車１２、太陽歯車２１と出力歯車１３とがそれぞれ一体化される。前記ばねクラッチ１８は、内歯歯車２３の一部に形成されたクラッチ外輪１９とキャリヤ２６の一部に形成されたクラッチ内輪２９との間に介在され該クラッチ外輪１９の内径面に緊縛されたコイルばね３６により構成される。前記コイルばね３６は、前記入力の正回転方向Ａのトルクを受けてロックする方向性を有し、前記制御歯車１７に設けたロック解除部３４をコイルばね３６のロック解除フック３７に係合させ、該コイルばね３６の他端部を前記キャリヤ２６に係合させる。
