The open and close unit includes a rotating disk (200) which is rotatably provided in a frame (100) and is connected to a torsion spring. A hook catch (201) which releasably locks a hook provided on the door is formed in the rotating disk. A moving path (210) is formed in one surface of the rotating disk such that two rotations of the rotating disk form one cycle. The frame has a guide groove (110) at a position facing the moving path of the rotating disk. The open and close unit further includes a ball (300) which is provided in a space defined by the guide groove and the moving path. Thereby, the open and close unit according to the present invention can re¬ peatedly conduct an operation of opening and closing the door using the ball which moves along the moving path formed in a rotating disk.</p> |
