PROBLEM TO BE SOLVED: To provide a support table whose inclination and height position of the support part can easily be adjusted. SOLUTION: The support body 10 is connected to rotation shafts 4, 6, 8 of the base. Spiral gears 20, 22 are equipped on both end parts of the drive shaft 18 in between the rotation shafts 4, 5. When the spiral gear 12 of the shaft 4 is engaged with the spiral gear 20, the shaft 4 is rotated by the rotation of the shaft 18. When the spiral gear 14 of the shaft 6 is engaged with the spiral gear 22, the shaft 6 is rotated by the rotation of the shaft 18. When the spiral gear 16 of the shaft 8 is engaged with the spiral gear 40 on one end part of the shaft 38, the shaft 8 is rotated by the rotation of the shaft 38. When the spiral gear 30 on one end of the shaft 28 in between the shafts 6, 8 is engaged with the spiral gear 14, the shaft 28 is rotated by the rotation of the shaft 6. When the spiral gear 32 on the other end of the shaft 28 is engaged with the spiral gear 16, the shaft 8 is rotated by the rotation of the shaft 28.
