Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a slewing gear of a lift-up device for building a tower structure excellent in application properties and safety and capable of safely building a rotary body such as large blades at an air position low from the ground even under a geographical condition not suitable for building on the ground. SOLUTION: In the lift-up device for building the tower structure mounting the rotary body 9 lifted up by the lift-up device 3 on a top end part of the tower structure 2 which is constructed by connecting unit members piled up in order by the lift-up device 3, the slewing gear 8 building the rotary body 9 in a horizontal plane is installed attachably and detachably on the lift-up device 3. Consequently, since the rotary body 9 such as the large blade can be safely built in the horizontal plane at the air position low from the ground G even under the geographical condition not suitable for building on the ground, large scale preparation construction or the like for building the rotary body 9 on the ground around the tower structure 2 is made unnecessary.
