PROBLEM TO BE SOLVED: To quickly wind thread on a plurality of bobbins held by a holder member by rotating the holder member at high speed. SOLUTION: A bobbin holder 5 includes: a winding shaft 23 rotatable on the axis; and a cylindrical holder member 25 connected to the distal end of the winding shaft 23 and detachably supporting the plurality of bobbins. In the holder member 25, a plurality of recessed parts 25b disposed in the circumferential direction at certain intervals and further aligned in the axial direction are formed. The bobbin holder 5 further includes a plurality of chuck pieces disposed correspondingly to the plurality of recessed parts 25b. The plurality of chuck pieces hold the plurality of bobbins attached to the holder member 25. The chuck piece includes: a chuck capable of pressing the bobbin attached to the holder member 25; a piece moving the chuck in a radial direction to approach/separate to/from the bobbin; and a spring energizing the piece in the direction of axially approaching the chuck (forward).
