Abstract

ボール(3)の無限循環路(30)を簡易な構成でスライド部材(2)に具備させることができると共に、スライド部材(2)と案内軸(1)を分離しても当該スライド部材(2)からボール(3)が脱落することのない直線案内装置であり、長手方向に沿ってボール(3)の転走溝(10)が配置された案内軸(1)と、前記ボール(3)が循環するトラック溝(30)を前記案内軸(1)に面して具備し、この案内軸(1)に沿って移動自在なスライド部材(2)とから構成され、前記トラック溝(30)は、案内軸(1)の転走溝(10)と対向して配置される負荷通路部(31)と、この負荷転走通路(31)と平行に設けられる無負荷通路部(32)と、これら負荷通路部(31)と無負荷通路部(32)とを連通連結してこれらの間でボール(3)を往来させる一対の方向転換通路部(33)とから構成されており、前記トラック溝(30)はその全周にわたり、前記案内軸(1)に向けた開口幅がボール(3)の直径よりも小さく設定されている。
