A metal deforming apparatus to be used for purposes such as automobile repairs. A frame of the apparatus carries a vertically movable support structure which in turn carries a gripping structure for gripping a part such as a vehicle body which is situated over the vertically movable support structure, a suitable structure being provided for vertically moving the vertically movable support structure with respect to the frame. A horizontal telescopic beam assembly is carried by the frame and is capable of having its length changed by a beam moving structure. A clamp is provided for clamping a part which is to be deformed or for clamping a tool which is to act on such a part. A positioning structure carries the clamp and is connected with the beam assembly for adjusting the position of the clamp. The structure which moves the vertically movable support with respect to the frame is capable of applying vertical pushing or pulling forces to a part which is to be deformed while the structure which changes the length of the telescopic beam assembly is capable of applying horizontal pushing or pulling forces to the part which is to be deformed.
