Abstract

　無負荷戻し通路のねじり量を少なくすることができるローラねじを提供する。 　ローラねじは、外周面に螺旋状のローラ転走面１ａを有するねじ軸１と、内周面にねじ軸１のローラ転走面１ａに対向する螺旋状の負荷ローラ転走面２ａを有するナット２と、ナット２に設けられ、ナット２の一巻き未満の負荷ローラ転走面２ａの一端と他端を接続する無負荷戻し通路８を有する循環部材７と、負荷ローラ転走路６及び無負荷戻し通路８によって構成される一巻きのローラ循環経路に配列される複数のローラ４と、を備える。循環部材７は、一巻き未満の負荷ローラ転走路６の一端まで転がったローラ４を無負荷戻し通路８に導き、一巻き未満の負荷ローラ転走路６の他端に戻す。負荷ローラ転走路６の巻き数が一巻き未満に設定されるので、負荷ローラ転走路６を移動するローラ４をそのままの姿勢で隣の負荷ローラ転走路６に移すことができる。
