Abstract
An embroidery frame includes a pair of a first frame and a second frame configured to clamp a sewing object, and a lock mechanism. The lock mechanism is configured to switch a position of the second frame with respect to the first frame to at least three positions including a first position, a second position and a third position. The first position is a position in which the second frame is closed with respect to the first frame. The second position is a position in which, with respect to the first frame, the second frame is more open, by a first predetermined amount, than in the first position. The third position is a position in which, with respect to the first frame, the second frame is open by a second predetermined amount. The second predetermined amount is larger than the first predetermined amount.
