To provide a yarn winding device allowing a large change of a contact pressure to a winding drive roller of a yarn package without replacing a component or using an actuator such as an air cylinder.

This yarn winding device has an energizing means. The energizing means has a moving member 41 movable in a direction perpendicular to the axis of a winding drive roller 2, a spring member 44 interposed between the moving member 41 and a cradle arm 13b, generating an energizing force energizing the cradle arm 13b to a prescribed direction, and operation members 45, 46 moving the moving member 41 to adjust the energizing force of the spring member 44 according to an operation input.
