A frame exchanging an advertisement sheet is provided to prevent the separation of a main frame and a cover frame by making them closely fixed. An advertise frame is made of a main frame(10) and a cover frame(20), and a hinge shaft(11) is protruded from one side of the main frame. The cover frame is not separated from the main frame by a hinge shaft while being rotated, and the hinge shaft is extended due to the main frame into one body. The hinge shaft of the main frame is inserted in a hook groove(21) of the cover frame. The curvature portion is formed in the outer side of the main frame. |
