Abstract
Provided is a rolling guide device which is capable of directly recognizing an operation condition of a moving member with respect to a track member or a circulation state of rolling elements in an endless circulation path, the rolling guide device including: a track member having a rolling surface; and a moving member, which is assembled to the track member through intermediation of a large number of rolling elements which roll on the rolling surface, and has an endless circulation path for the rolling elements, the moving member including: a main body member having a load rolling surface and a no-load return path for the rolling elements, the load rolling surface being opposed to the rolling surface of the track member to define a load path for the rolling elements, a pair of covers, which have direction change paths for allowing the rolling elements to move between the load path and the no-load return path, and is mounted to the main body member; and a measurement plate, which is interposed at least between the main body member and one cover to form part of the endless circulation path, and has a mounting portion for a sensor configured to detect an operation condition of the mo…
