Abstract

　運動案内装置の剛性を変化させることができると共に、移動ブロックに大荷重がかかるときに、移動ブロックのスライド抵抗が増加するのを抑制できる運動案内装置を提供する。 　運動案内装置の転動体循環経路に配列する複数の転動体列１４ａ，１４ｂ，１４ｃを、移動ブロック１２にかかる荷重が所定値未満のときにも、所定値以上のときにも荷重を負荷する第一の転動体列１４ａ，１４ｃと、移動ブロック１２にかかる荷重が所定値未満のときに荷重を負荷せずに、所定値以上のときに荷重を負荷する第二の転動体列１４ｂと、で構成する。第一の転動体列１４ａ，１４ｃは、軌道部材１１に対する移動ブロック１２の相対的な運動に伴って、転動体循環経路を循環する。第二の転動体列１４ｂは、移動ブロック１２にかかる荷重が所定値以上のとき、軌道部材１１に対する移動ブロック１２の相対的な運動に伴って、転動体循環経路を循環する。
