Abstract

　このリニアアクチュエータは、駆動モータ２と、駆動モータ２を収容するシャフト部４と、駆動モータの回転軸２ａに回転可能に連結されるとともに、その外周面に雄ねじ部５ａを有する出力部材５と、出力部材及びシャフト部の外周に配置されるとともに、その内周面に雄ねじ部の回転を受ける雌ねじ部６ａを有する従動部材６と、シャフト部と従動部材との相対的回転を規制する回転規制部１０と、回転軸の軸線Ｃ方向のスラスト荷重を受ける軸受け部１２とを備える。このリニアアクチュエータによれば、駆動モータの回転軸周りに部材がふら付くことなく高精度な位置決め・送りが可能であり、また直線運動のストロークが比較的長く確保でき、スラスト荷重に対する強度が確保され、装置を安価且つコンパクトに構成することができる。
