To provide a disc-transfer roll (1) for use in a disc device (10) which can firmly hold and transfer a disc (D) without slip, it comprises a hollow cylindrical body (2) of an elastic material and a cylindrical support body (3) press-fitted in the hollow cylindrical body. The hollow cylindrical body (2) has a plurality of spline slots (2a) formed on its inner circumference, whereas the cylindrical support body (3) has another plurality of spline ridges (3a, 3c or 3d) to define predetermined unfilled spaces (2a, 3e, 5, 6 or 7) between the concentric cylindrical bodies (2 and 3) (Fig. 1). <IMAGE> <IMAGE> <IMAGE>
