- 装置本体の内部にネジ軸を回転可能に配設するとともに、このネジ軸に並設する態様で電動モータ及びバッテリを配設して成り、前記バッテリを電源として前記電動モータを駆動し、前記電動モータによって前記ネジ軸を回転させることにより、前記ネジ軸に螺合するスライド部材を前記ネジ軸の軸心に沿って移動させるようにした直動装置において、
前記ネジ軸の基端部延長域に前記ネジ軸の軸心を中心として遊星歯車機構から成る減速機構を構成し、かつ前記減速機構の出力要素を前記ネジ軸の端部に嵌合させるとともに、前記減速機構の入力要素と前記電動モータの駆動軸との間に動力伝達機構を介在させ、
前記動力伝達機構は、前記電動モータの駆動軸から入力ギヤまでの間において前記電動モータの回転を減速するように構成され、
前記入力ギヤに格子円板が設けられているとともに、前記格子円板を介して前記入力ギヤの回転を検出するフォトセンサが前記装置本体に設けられていることを特徴とする直動装置。 - 前記減速機構は、直列に接続した2組の遊星歯車機構を備え、
前記減速機構を構成する前段の遊星歯車機構は、前記動力伝達機構によって回転されるサンギヤと、前記装置本体に固定したアウタギヤと、これらサンギヤ及びアウタギヤに歯合するプラネタリギヤとを有し、前記プラネタリギヤを支持するプラネタリキャリヤが出力となるように構成したものであり、
前記減速機構を構成する後段の遊星歯車機構は、前段のプラネタリキャリヤに設けたサンギヤと、前記装置本体に固定したアウタギヤと、これらサンギヤ及びアウタギヤに歯合するプラネタリギヤとを有し、前記プラネタリギヤを支持するプラネタリキャリヤが出力となるように構成したものであり、
前記後段の遊星歯車機構のプラネタリキャリヤに前記ネジ軸の端部を嵌合させたことを特徴とする請求項1に記載の直動装置。
