PROBLEM TO BE SOLVED: To facilitate work of installing a driving means and reduce noises during driving in rotation by engaging a roller connector which is concentric with a turntable and installed along the circumferential direction and a driving sprocket provided on the boom side with the turntable surrounding a bucket elevator. SOLUTION: On the lower side of a turntable 3, a roller connector 9 is installed through a fitting bracket 18 and a bolt on the radial outside of a ring-like bracket 21 which is concentric with the turntable 3 and extended downward. On the radial outside of the roller connector 9, a driving sprocket 11 engaged therewith is provided on the boom side through a motor 22 and a speed reducer 23. The lower surface of the turntable 3 is provided with a ring-like driving rail 24 concentric with the turntable 3, and a support roller 25 abutting against the lower end surface of the lower side thereof and a side roller 26 abutting against the radial inside surface are arranged in three places in such a manner as to offset from each other by equal pitches in the circumferential direction.
