Abstract: Provided is a device for opening and closing a sliding door, of which collinearly placed doors slide respectively to overlap each other such that the sliding door is opened or closed. The device includes a sliding portion formed on a surface on which doors come into contact with each other in order to prevent the doors from interfering with each other when the doors are opened; a pair of rail frames formed on a top surface of the furniture and provided with a rail protruding upwardly such that each door is slid forward and backward on the rail, the rail having both sides in which bending portions are formed; and rotational members, each of which is installed to one side of a connection bracket to be rotatable in a curved section of the bending portion while being lifted and slid on the rail.
