Referring to the first figure, the present invention relates to a floating disc tray 100 which mainly comprises a disc body 1 and a plurality of floating clasps 2. The disk body 1 includes an inner disk 11 and an outer disk 12 disposed on the outer periphery of the inner disk 11. The center of the inner disc 11 defines a central opening 13 for passage through an axle (not shown). In addition, the disk body 1 defines a plurality of spaced-apart coupling holes 10 between the inner disk 11 and the outer disk 12 (second drawing). The floating buckles 2 are correspondingly disposed on the coupling holes 10 to assemble the inner disk 11 and the outer disk 12 together.

As shown in the second figure, the inner disk 11 defines a plurality of spaced-apart half holes 110 along its outer periphery. On the contrary, the outer disk 12 defines a plurality of semi-holes 120 spaced apart at its inner periphery, corresponding to the half holes 110 of the inner disk 11 respectively. The half hole 110 of the inner disk 11 is opposed to the half hole 120 of the outer disk 12 to constitute the above-mentioned coupling hole 10.
