Abstract
A curvilinear motion rolling guide unit is such that pipe members adapted to form return passages are disposed respectively at undercuts of wings of an arcuate casing, thereby reducing working costs. A slider has a casing and end caps fixed to respective opposite ends of the casing. Pipe members adapted to form return passages are disposed at the respective undercuts formed on the wings of the casing. Cover members have longitudinally extending grooves, respectively, for covering the pipe members. Fitting grooves formed at opposite ends of the grooves of the cover members are fitted to direction changing passages provided in the respective end caps, whereby the cover members are fixed to the end caps.
