EMBROIDERY FRAME

An embroidery frame includes an outer frame formed into a substantially annular shape and having a discontinuity formed by partially breaking its annularity so that the outer frame has two ends located opposite each other with the discontinuity being interposed, an inner frame configured to be fitted with an inner periphery of the outer frame, a clamping mechanism clamping the outer frame against the inner frame and including paired screw-supporting members mounted on the outer frame ends and an adjusting screw mounted on the screw-supporting members so as to adjust a gap between the screw mounting members, and an operating knob supported on an operating end of the screw so as to be switchable between a first position where the knob extends parallel to an axial direction of the screw and a second position where the knob extends in a direction substantially perpendicular to the axial direction.
