PROBLEM TO BE SOLVED: To obtain a long durability life of a bearing while enabling high winding up speed operation even if a winding up spindle is a long cantilever style and to increase bending strength of the winding up spindle which is indispensable for increasing length of the cantilever by improving a spindle of a winding up machine. SOLUTION: It this winding up machine for winding up yarn around a bobbin 3.2, a spindle capable of chucking a bobbin winding tube 3.1 for supporting a bobbin 3.2 is provided, the spindle is composed of substantially tubular spindle main body 2, the spindle main body is connected to a shaft 4 pivotally supported in a fixed cantilever style spindle support body 1 via bearing devices 5.1, 5.2, and the bearing devices 5.1, 5.2 are composed of a plurality of rolling bodies 7, an inner guiding race 4.2 and an outer guiding race 8.2 guiding the rolling bodies 7, the inner guiding race 4.2 is directly formed on the shaft 4.
