Abstract
A rolling guide device is capable of preventing a scooping piece formed on a circulation path module from being deformed along with use over time, and enhancing the durability of the scooping piece, thereby achieving smooth motion of a moving member relative to a track member. A moving member includes: a main body member having load rolling surfaces and return paths for rolling elements; direction change pipes having formed therein inner direction change paths and having inner peripheral guide surfaces of outer direction change paths, respectively; and lid members each being mounted on the main body member and having outer peripheral guide surfaces of the outer direction change paths. Each of the direction change pipes includes: a first half circulation segment and a second half circulation segment; and a scooping portion for guiding the rolling elements into each of the inner direction change paths.
