Abstract
PURPOSE:To raise the accuracy of concentricity, and to prevent the rotational deflection of a rotary drum by providing a cylindrical body on both the surface and the reverse side of the rotary drum, and fitting and attaching a clamping member to both of these cylindrical bodies. CONSTITUTION:By an expanding rod which is inserted into a rotary drum 5, a clamping member 22 which is fitted and attached to both the surface and the reverse side of the rotary drum 5 is expanded in advance, the rotary drum 5 is inserted into a rotation axis 3, and thereafter, the expanding rod is removed and cylindrical bodies 21a, 21b are clamped to the rotation axis 3 by elastic shrinkage force of the clamping member 22, and the rotary drum 5 is fixed to the rotation axis 3. Accordingly, the clamping member 22 can be placed on both the surface and the reverse side of the rotary drum 5. In such a way, a span of a pair of clamping members 22 can be taken long enough and a rotational deflection of the rotary drum 5 can be minimized, and also, since the part projected to the upper part from the rotary drum 5 can be shortened, it can be realized to form the titled device to a thin type.
