PROBLEM TO BE SOLVED: To provide a rotary driver preventing an uneven load in a screw shaft, a bearing or the like and easy generation of malfunction by preventing connection failure of a connecting part due to misalignment or the like due to thermal expansion or defective manufacture in the connecting part of a power transmission mechanism of the rotary driver. SOLUTION: The rotary driver is provided with a driving part rotating to generate torque, an output part connected to a driven part so as to transmit power of the driving part to the driven part, and the power transmission mechanism transmitting the power of the driving part to the output part. The power transmission mechanism is provided with a driving part side connected to the driving part, an output part side connected to the output part, and the connecting part to which the driving part side and the output part side are connected. A power transmission intermediate part intervened between the driving part side and the output part side to transmit power from the driving part side to the output part side is provided in the connecting part.
