(54) YARN WINDER


(57) The present invention provides a yarn winder with:
a cradle device 21 which has a cradle arm 31 that rotatably supports a bobbin B and which is capable of moving the cradle arm 31 in a predetermined direction crossing the axial direction of the bobbin B; a vibration suppression lever 41 that is pressed against the cradle arm 31 and thereby suppresses the vibration of the cradle arm 31; and a pressing mechanism 61 that pushes the vibration suppression lever 41 against the cradle arm 31. The pressing mechanism 61 is capable of changing the magnitude of the pressing force during the winding operation of a yarn Y and, during the winding operation, a control unit 13 changes the magnitude of the pressing force, sets the magnitude of the pressing force at a first pressing force when an arm driving unit 37 is not driven, and sets the magnitude of the pressing force at a second pressing force when the arm driving unit 37 is driven.
