Description
Claims (2)
- 正転及び逆転が可能なモータの回転出力軸が、円柱状外周面を有する案内回転体に動力の伝達を可能とされており、
前記案内回転体には、らせん状の疎巻きのコイルバネが前記案内回転体の軸方向に移動可能に巻装されており、
前記コイルバネの両端において、前記案内回転体の外周側に延出した部分に形成された2つの延出部が、移動部材に係合されることにより、前記コイルバネの回転が阻止されており、
前記案内回転体は、外周面の軸方向中間部の同心円上の周方向複数位置に形成された複数の突起を含み、
前記複数の突起のうち、第1の突起は、前記案内回転体の一方向への回転によって前記コイルバネのピッチ間隙に対し、前記ピッチ間隙の螺旋状の長手方向に沿って相対的に移動されることにより、前記コイルバネと係合して前記コイルバネを軸方向に移動し、
前記第1の突起は、前記ピッチ間隙の螺旋状の長手方向の端に達した後、前記コイルバネとの係合が解除され、前記第1の突起と前記コイルバネとの係合が解除されたときに、前記複数の突起のうち、第2の突起と前記コイルバネとが係合する、
電動アクチュエータ。 - 請求項1に記載の電動アクチュエータにおいて
前記複数の突起の数は、2つ~4つのいずれか1であり、前記案内回転体の同心円上の周方向複数位置に均等に配置される、
電動アクチュエータ。
