Abstract
A bobbin holder mounted on a yarn winding machine includes a plurality of chucking members disposed at an outer periphery of the holder. The chucking members are expanded radially outwardly so as to engage an inner side of a cylindrical bobbin coaxially inserted onto the holder when they are longitudinally compressed. The chucking members release the bobbin when they are moved radially inwardly. The portions on the holder for receiving the chucking members are formed as concaves, with a part of each chucking member inserted into a respective concave.
