Abstract
Abstract A vehicle-measuring machine which is used to measure positional deviation from any desired vehicle reference point when, for example, a mechanic is inspecting or repairing the vehicle. When a conventional model of this kind of vehicle-measuring machine is used, detecting and correcting any error is difficult because the vertical direction indicated by a vertical member can deviate from the vertical axis of the vehicle owing to the inclination of the vehicle. According to the present invention, an angle-varying unit is provided which varies the angle of each of lifting members with respect to a mount in various directions, i.e., longitudinally, laterally, and composites thereof, in accordance with the inclination of the vehicle, using the weight of the mount. This automatically shifts a reference portion corresponding to the deviation of the vertical member, thereby automatically correcting the error.
