PURPOSE: To easily attach or detach two discs by radially providing an elastic piece at the periphery of a central hole and providing a columnar part protruding from one of front and rear surfaces at the free end of each piece in a tray for a disc in which the two discs each having a through hole at the center are detachably held at the front and rear surfaces. CONSTITUTION: A circular central hole 12 is formed at the center of a flat platelike tray body 11, a plurality of radially cut through grooves 13 are provided from the hole 12 radially outward at the periphery of the hole 12 to form a plurality of beamlike elastic pieces 14 in which the radial inward parts are free ends 14a. Columnar parts 15, 16 alternately protruding at the front surface 11a side and the rear surface 11b side of the body are formed at the adjacent pieces 14, and cantilever beamlike pressing parts 17, 18 are formed at the ends of the parts 15, 16. The parts 15, 16 and 17, 18 constitute disk holders 19, 20, thereby holding the discs at the holes. |
