A rolling guide device is capable of facilitating smooth circulation of rolling elements in an endless circulation path, and enhancing the accuracy of motion of a moving member relative to a track member. The moving member includes: a main body member having load rolling surfaces and return paths for the rolling elements; direction change pipes incorporating 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. The main body member has position reference holes formed therein so as to serve as position references for the direction change pipes, respectively, whereas the direction change pipes have positioning protrusions formed thereon so as to be press-fitted into the position reference holes, respectively. Further, the direction change pipes include rotation restriction protruding portions. |

1. A rolling guide device, comprising:
a track member; and a moving member assembled to the track member through intermediation of a large number 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 large number of rolling elements;direction change pipes incorporating the inner direction change paths and having inner peripheral guide surfaces of the outer direction change paths, respectively; andlid 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, and 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. |
