Rolling guidance device

A rolling guide device, comprising:

• a track member;
• and
• a moving member assembled to the track member through intermediation of a multitude of rolling elements, the moving member having formed therein a plurality of rolling-element endless circulation paths comprising inner direction change paths and outer direction change paths overlapping with each other,
• wherein the moving member comprises:
• a main body member having load rolling surfaces and return paths for the rolling elements;
• direction change pipes having formed therein the inner direction change paths and having inner peripheral guide surfaces of the 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, and
• wherein each of the direction change pipes comprises:
• a first half circulation segment and a second half circulation segment divided in a plane forming a corresponding one of the inner direction change paths;
• and
• a scooping portion for guiding the rolling elements, which are rolling along each of the load rolling surfaces, into the corresponding one of the inner direction change paths, the scooping portion being formed only on the first half circulation segment without being formed on the second half circulation segment.
