PROBLEM TO BE SOLVED: To provide a support device for slewing structure of which versatility is improved by freely setting the slewing angle of a slewing structure regarding the support device for slewing structure. SOLUTION: The support device for slewing structure is so constituted that the slewing shaft 2 of a slewing structure 1 is supported freely rotatably at a shaft support part 3, and at the same time, a slewing range of the slewing structure 1 is regulated by accepting a guide shaft 4 in parallel with the slewing shaft 2 inside an arcuate guide groove 5 coaxial with the shaft support part 3. The support device for slewing structure has a blocking member mounting part 6 and a groove blocking member 7 fixed at the blocking member mounting part 6 to block an arbitrary range of the guide groove 5 and to change the slewing angle of the slewing structure 1.
