PROBLEM TO BE SOLVED: To provide a rotary auxiliary device capable of retaining safety of a columnar rotary press-in machine and making exchangeable to the revolution by only an existing motor without troubles when a load of a columnar material revolution is reduced by a rotary asist. SOLUTION: One end of a columnar material is connected to the output shaft of a rotary driving part including a motor supported to a leader mast to be vertically movable and suspended therefrom, this columnar rotary press-in machine is constituted so as to support the rotary auxiliary device at the lower part of the leader mast. The rotary auxiliary device rotatably has a rotary body surrounding a columnar material having a chuck device to detachably hold the outer peripheral face of the columnar material and a circular swingable body concentrically positioning at the outside of the rotary body and a vibrating driving means vibrating the upper moving body. The circular circulating body and the rotary body are connected to each other to transmit the vibration to the rotary body in vibrating in one direction of the vibratory body and it is disconnected in the other directional vibration, one way clutch mechanism mutually vibrating while disconnecting the joint body is provided between the vibration body and the rotary body.
