8 is a curved surface, the curvature of the curved surface 28 is the support plate 3
1 is smaller than the curvature of the inner surface. Also, a large number of grooves 29 or ridges 30 are formed on this surface 28. Therefore, the rubber-like elastic body 22 and the support plate 31 is varied with to change the weight of the rotary drum 35 to contact each other by this structure. That is, when a lot of clothes containing a large amount of moisture are stored in the rotating drum 35, the large weight of the rubber-like elastic body 22 causes a large elastic deformation and a large contact area, thereby increasing load resistance. As the drying proceeds gradually and the weight gradually decreases, the contact area gradually decreases. Therefore, the rotary drum 35 is always supported with an appropriate elasticity, and noise due to rattling can be suppressed to a small level.
