(54) Bobbin holder support structure


(57) The present invention provides a bobbin holder support structure that allows the natural frequency of a bobbin holder to be greatly varied in order to prevent resonance over a wide range of available rotations. The present invention enables a bobbin holder 5 to be rotatably supported at two root-side positions using support members 11, 12 so that the bobbin holder 5 can be supported like a cantilever, while enabling the tip side of the bobbin holder to be rotatably supported using a detachable support member, and provides an offset absorption member 14 in a support structure comprising one 12 of the root-side support members. Consequently, with the tip of the bobbin holder 5 supported, the bobbin holder 5 is arrested and supported substantially at the two positions in a radial direction using the other root-side support member 11 and the tip-side support member 13. Interposing vibration absorption members 23, 23 are provided for a support structure comprising the other root-side support member 11. Interposing vibration absorption members 24, 24 are provided for a support structure comprising the tip-side support member 13 (Fig. 2A).
