A bobbin holder comprises a rotatable support member, a plurality of bobbin holding devices inserted onto the rotatable support member, and at least one cylindrical member inserted onto the rotatable support member and engaging with the bobbin holding device, so that bobbin holding devices are expanded so as to hold bobbins. A main compression member for radically expanding the bobbin holding devices is disposed at one end of the bobbin holder. At least one supplementary compression member for supplementing expansion force of the main compression member is disposed at an intermediate portion between a bobbin holding device located at the end where the main compression member is disposed and another bobbin holding device located at an opposite end.
