SOLUTION: A stepped surface 15 which is located at a position being higher than the lower ends of a column 1 and a horizontal post 5 is installed on the internal end section of a female-threaded hole 24 for attaching an adjuster to the lower end of the right and left columns 1. The attaching piece 16 of a caster attaching member 14 keeps a caster 17 attached to the lower surface of the stepped surface 15. The external side end of the attaching piece 16 is brought into contact with the internal surface of the column 1 directly under a lower section connecting rod 3, and the attaching piece 16 is fixed with a bolt 23.
