Abstract
In order to reduce the amount of play of balls in a circulation path in a linear guide device to thereby reduce the noise during the running of the linear guide device and improve the quality and productivity of the device, the communicating portion of the straight portion of a ball circulation path in a slider body and the curved portions of ball circulation paths in end caps is constituted by faucet-fitting comprising a cylindrical convex portion provided so as to extend the curved portions relative to the communicating portion and a cylinder concave portion corresponding to the cylindrical convex portion provided in the straight portion.
