Rolling guide device

A rolling guide device, comprising:

• a track member;
• and
• a moving member assembled to the track member through intermediation of a plurality of rolling elements, the moving member having a plurality of rolling-element endless circulation paths comprising inner direction change paths and outer direction change paths intersecting with each other,
• wherein the moving member comprises:
• a main body member having load rolling surfaces and return paths for the plurality of rolling elements;
• direction change pipes, each incorporating one of the inner direction change paths, and having an inner peripheral guide surface for one 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,
• wherein the main body member, to which the direction change pipes are fixed, has position reference holes formed therein so as to serve as position references for the direction change pipes, respectively,
• wherein the direction change pipes have positioning protrusions formed thereon so as to be press-fitted into the position reference holes, respectively,
• wherein the direction change pipes comprise rotation restriction protruding portions formed on outer wall portions of the inner direction change paths, respectively, for preventing rotation of the direction change pipes about the respective positioning protrusions when the lid members are fixed to the main body member,
• wherein the rotation restriction protruding portions each include a columnar restriction portion which has a columnar shape and protrudes toward the lid members from the outer wall portions of a respective one of the inner direction change paths of a respective one of the direction change pipes,
• wherein each of the lid members has receiving grooves for the direction change pipes, and
• wherein the receiving grooves each have a locking hole formed therein, such that the columnar restriction portions are fitted into the locking holes, respectively.
