PROBLEM TO BE SOLVED: To provide a bobbin chuck device capable of facilitating extracting a bobbin with a chuck piece certainly separated from the bobbin in releasing and extracting the bobbin from a bobbin holder, and capable of attaining wall thinning and high-speed handling of the bobbin holder. SOLUTION: A chuck piece 3 includes a first member 5 for the bobbin 52 and second members (4, 6) for a rotating cylinder 51. The first member 5 and the second members (4, 6) relatively approach or are separated from each other in the axial direction of the rotating cylinder 51, so that the first member 5 and the second members (4, 6) are respectively energized toward or released from the bobbin 52 and the rotating cylinder 51. When the first member 5 and the second members (4, 6) are relatively moved so that both of the members may be respectively energization-released, both of the members are kept in mutual engagement, and an engagement part for separating the first member 5 from the bobbin 52 is provided on the first member 5 and the second members (4, 6) respectively.
