PROBLEM TO BE SOLVED: To inhibit contact damage and exfoliation of paint film on an outer circumference surface of a pipe body when the pipe body after painting is supported. SOLUTION: A receiving groove 12 on which an outer circumference surface of the pipe body P after painting is mounted is formed on a pipe body pedestal 11, and a pair of support projections 13 is provided in the receiving groove 12. The pair of support projections 13 is formed in a hemispherical shape and support an outer circumference lower surface of the pipe body at outer circumference surface of the pair of the support projections 13. If a pipe axis and a center line of the pair of the support projections 13 slip under a support condition, the pipe body P drops along the outer circumference surface of one of the support projections 13 by own weight thereof when the pipe body P butts on a tip of the outer circumference surface of one of the support projection 13. At that time, circumference direction length of a section where the outer circumference surface of the pipe body P contacts the outer circumference surface of one of the support projections 13 gets shorter than circumference direction length of a contact section when the pipe body P drops along a groove side surface of the receiving groove like as a former unit. Consequently, a contact section of the outer circumference surface of the pipe body P and the outer circumference surface of the support projections gets narrow to inhibit exfoliation of paint film.
