PROBLEM TO BE SOLVED: To roughly completely avoid unallowable vibration generated in structure groups while yarns are wound up on a bobbin in a device for winding up the plurality of yarns on the bobbin mounted on a drivable bobbin spindle. SOLUTION: This device comprises a plurality of traverse units 7.1 and 7.2 disposed correspondingly to the yarns and a pressing roller 6 disposed between these traverse units and the bobbin spindle 3.1. The bobbin spindle 3.1, the traverse unit, and the pressing roller 6 are held by the frame parts 1.1, 1.3, and 1.4 of a machine frame 1 in the form of structure groups independent of each other. Each of the structure groups comprises a prescribed natural frequency. The plurality of yarns 21 are wound up on the bobbin 5 mounted on the drivable bobbin spindle 3.1. Also, the device comprises a means 10 affecting the rigidity of the frame 1.3 by at least one of the frame parts 1.1, 1.3, and 1.4 to change the natural frequency of each of the structure groups during the yarn windup operation.
