PURPOSE:To make it possible to easily attach or detach a turnable and a roller so that the interior of a heating chamber can be easily cleaned, by integrally forming supporting parts for mounting roller, on the back of the turnable. CONSTITUTION:A turnable 6 is formed by a plastic material, and an engaging part 6b and three supporting parts 6a are integrally formed at the center the back 6e so that these supporting parts 6a are equally disposed on a core circle around the engaging part 6b. Slits 6c and 6c are formed into a front rear circle shape where the inlet dimension of W of slits 6c and 6c is smaller than the diameter d1 of a press fit shaft 9a, and the diameter d2 of the rear circle part is made larger than the diameter d1 to smoothen the rotation of a press fitting shaft 9a. The press fitting shaft 9a of the roller 9 is press fitted in the slits parts 6c and 6c of the supporting parts 6a, and the press fitting shaft 9a is positioned at the rear circle part of the seating parts 6c and 6c, and the engaging part 6b of the turnable 6 fitted with a roller 9 is fitted in the rotary shaft 10a of a motor 10 via a driving part 11. Since the turnable 6 and the roller 9 is attachable and detachable in such a form that they are integrally assembled, cleaning of the interior of the heating chamber, the turnable 6 and the roller can be easily cleaned.
