ABSTRACT:
An embroidery frame includes an outer subframe with a section that breaks continuity, an inner subframe that is snapped inside of the outer subframe to hold a cloth with the outer subframe, a clamp mechanism for clamping the outer subframe against the inner subframe. The clamp mechanism includes a pair of screw attachment sections facing each other at both ends of the continuity-breaking section of the outer frame, an adjustment screw attached across the screw attachment sections for adjusting a space between the screw attachment sections, an operation shaft for rotating the adjustment screw that moves in a range from a first position at which the operation shaft is directed in an axial direction same as or different from the adjustment screw, and a second position at which the operation shaft is tilted in a direction increasing a space with the outer subframe, and a coupling mechanism for coupling together the operation shaft and the adjustment screw, and transferring a torque of the operation shaft to the adjustment screw.
