ABSTRACT:
In this rolling guide unit, a slider is provided on a track rail so that the slider can be moved slidingly in a linear direction, and a circular bore is formed in a casing constituting the slider. A cross-sectionally V-shaped outer annular raceway surface is formed on the circumferential surface of the circular bore, and a rotary body consisting of lower and upper rotary bodies is fixed rotatably in the same circular bore. The casing constitutes a common part having both a function of making a linear movement and a function of making a rotational movement. This enables the height of the rolling guide unit to be reduced to as great an extent as possible, and an accumulated error due to an assembling operation to be minimized, so that a highly accurate guide machine can be provided.
