PURPOSE:To prevent measurement from the generation of an error even if the positions of relative parts are shifted by arranging angle varying parts varying angles of respective suspending bodies from the base board by the weight of the base board in the front and back, right and left and their composite directions in accordance with the inclined angle of the car body. CONSTITUTION:The suspending bodies 9, weights 19 and reference parts 13 are set up to required conditions in accordance with the arrangement of a selected reference point of the car. The weights 19 are shifted from the Z axis direction of the car body 1, and even if the positions of the relative parts 17 are shifted, the positions of the reference parts 13 are automatically shifted in the same direction as said shift by the same distance as said shift through the angle varying parts 30, 31 changing the directions optionally by the weight of the base board 7. Thus, the direction and distance of the car reference point shifted from the normal position can be detected by observing the shift of the positions of the relative parts 17 from the reference parts 13. |
