SOLUTION: A coupling device couples the corners of a plurality of frame members which form a frame body, for example, a frame, a poster frame, and a jigsaw puzzle frame. The coupling device has a base board which rotatably attaches each of the ends of the frame members at right angles to its axial direction, a lock means which is attached to the base board and locks each of the frame members with the frame members closed inside, and a corner member which smoothes a corner that forms each of corner parts of the frame body. The corner member is attached to the base board swingably. COPYRIGHT: (C)2005,JPO&NCIPI
