A vent equipped with an edge supporting member is provided to prevent the front end of the edge from sagging by fixing a vertical frame and a horizontal frame. A vent equipped with an edge supporting member comprises a mainframe and a vent frame. The mainframe is installed at the wall. The vent frame is formed inside the mainframe. The vent frame comprises a pair of vertical frames(40) and horizontal frames(50). A guide piece(46) is formed at the outer side(42,52) of the vertical and horizontal frames and the inner side of diaphragms(43,53). The guide piece is protruded to face each other. Mounting grooves(47,57) are formed between the guide piece and the front sides(41,51) of the vertical and horizontal frames. The edge supporting member(60) is mounted on the mounting groove. The edge supporting member integrally connects the vertical and horizontal frames. The edge supporting member maintains the rectangular shape of the horizontal and vertical frames. |
