The casing constitutes a common part having a function of making a linear movement and a function of making a rotational movement, and 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, whereby a highly accurate guide machine can be provided.
