To provide a winding shaft device capable of reducing the minimum torque transmitted from a gripping device B to a winding core, and winding with a low tension from the beginning of winding, by arranging on a winding shaft alternately, a gripping device A having only a gripping function of the winding core without torque transmission and the gripping device B for gripping the core with rotary driving force by friction slide.

In a device in which a core gripping chuck member and a torque transmission member for connecting it to a shaft body are formed as one gripping unit 05, and a plurality of gripping units are mounted on the shaft body 01, a gripping device 05 for gripping a core in the static state and not having a torque transmission function, and a gripping device for gripping the core with rotary driving force are mounted on a shaft alternately in parallel, and the gripping device 15 is mounted on the shaft through a bearing 16, and set so as to be able to transfer a driving force from the shaft to the core by a friction force, and to select connection or non-connection to the adjacent gripping device.
