PURPOSE:To correct errors caused by the deviation from the vertical direction indicated by a vertical body due to the inclination of a vehicle automatically, by providing a variable angle part, which changes the angle of each suspending body with respect to a base table by the weight of the base table in correspondence with the inclination of the vehicle. CONSTITUTION:The angle of each suspending body 6 with respect to a base table 4 is changed by the weight of the base table in correspondence with the inclination of a vehicle 10 to front and rear and right and left and to the composite direction thereof by using variable angle part 24. The parts 24 are provided directly below a connecting part 8 of each suspending body 6 and in a major frame 22 of each lateral bar 2. Reference point parts 14 at the connecting parts 8 of the four suspending bodies 4 and one vertical body 17 are connected to corresponding vehicle reference points 9a and 9b. The base table 4 and the vertical body 17 are suspended from the vehicle 10. At this time, even though the vertical direction indicated by the vertical body 17 is deviated from the up and down direction of the vehicle 10 by the inclination of the vehicle 10, a reference part 12 is automatically deviated in correspondence with said deviation. Therefore, the error caused by the deviation due to the inclination of the vehicle 10 can be automatically corrected. |
