<p>According to the present invention, in a sewing machine, a cylindrical frame for retaining tubular objects is mounted integrally on a cylindrical drive ring that is reciprocally driven in a rotational direction around a cylinder bed and that is linearly reciprocally driven along an axis of the cylinder bed; the drive ring is rotatably supported by a support member that is arranged to contact the outer periphery of the drive ring at three or more positions. By utilizing this construction, not only the drive ring, but also the frame that is mounted thereon may have a small diameter, and the drive ring can be stably supported by the support member so that it smoothly rotates. As a result, the frame can retain tubular objects having a small diameter, such as golf club covers and wrist bands, and a sewing operation, such as an embroidery operation, can be suitably performed along the periphery of the tubular object. <IMAGE></p> |
