A car frame measuring apparatus is disclosed, which has a three-dimensional measurement assembly comprising a pair of x-axis units, a y-axis unit mounted for longitudinal movement on the x-axis units and having a center piece provided at the center, a pair of z-axis unit bases mounted for transversal movement on the y-axis unit, z-axis unit holders each mounted on each z-axis unit base and provided with a z-axis unit capable of being extended by a spring, and a center piece having each end coupled by a chain to each z-axis unit. The opposite side z-axis units can be made to be at an equal distance from the center of the y-axis unit by aligning the last mentioned center piece and the center piece on the y-axis unit.
