This linear motion rolling guide unit is able to detect the relative positions and so forth of a track rail and slider by forming narrow grooves 21e in track rail 21 and arranging extremely narrow, linear scales 31 and 32 in those grooves. Thus, it is easy to reduce the size of this linear motion rolling guide unit, it is able to flexibly accommodate the particular conditions of use, and it is also inexpensive.
