Abstract

　ストローク範囲の全域に亘って確実な防塵機能を発揮することの可能な防塵機構付きリニアアクチュエータを提供する。 　防塵機構付きリニアアクチュエータ１００は、ボールねじと、ボールねじに係合するボールねじナットを有し、ボールねじの回転運動にともなって該ボールねじの軸方向に往復直線運動自在とされる移動ステージ４と、少なくともボールねじを覆って設置されるハウジング部材２と、移動ステージ４の移動軌跡に沿ってハウジング部材２に形成される開口部２７，２８と、開口部２７，２８を封鎖するためにハウジング部材２の内側に配置される防塵ベルト２９，３０と、を備える装置である。そして、この防塵機構付きリニアアクチュエータ１００は、ハウジング部材２の端部側を覆うエンドプレートカバー１０５ａ，１０５ｂを備えることにより、高い防塵性能を有している。
