Example An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 21 is an outer frame, 22 is a motor, and the motor 22 drives a rotating drum 25 and a fan 26 via belts 23 and 24, respectively. The rotation of the fan 26 causes a flow of air as indicated by the arrow b, and the hot air that has passed through the heater 27 dries the clothes 28 that are rotationally stirred in the rotating drum 25. The rotating drum 25 has a substantially cylindrical opening flange portion.
29, and a felt 31 that enhances airtightness is attached to the outer periphery of the support plate 30 that internally supports the flange portion 29, and a radial thrust bearing 32 formed in a substantially U shape is provided. Several are attached. The radial thrust bearing 32 has a radial bearing portion 33 that comes into contact with the inner surface of the flange portion 29 of the rotary drum 25 and a thrust bearing portion 35 that comes into contact with the side surface 34 of the rotary drum 25, and is formed in a substantially U-shape. ing.

With the above configuration, when the rotating drum 25 rotates to stir the clothes 28, the radial direction of the rotating drum 25 is regulated by the radial bearing portion 33 of the radial thrust bearing 32, and the rotating drum is rotated by the thrust bearing portion 35. twenty five
The thrust direction is also regulated and stabilized. Therefore,
Conventionally, it is possible to solve the problem that the end surface of the flange portion 29 of the rotary drum 25 hits the support plate 30 to generate a rusting noise. Further, since the thrust bearing portion 35 is only in contact with the side surface 34 of the rotary drum 25, the durability of the entire bearing is not deteriorated, and the number of radial thrust bearings 32 can be small and effective. .

EFFECTS OF THE INVENTION As is clear from the above embodiments, according to the present invention, it is possible to regulate the positions of the rotary drum in the radial direction and the thrust direction with a simple structure, and prevent problems such as a rustling noise due to the end face of the rotary drum flange be able to. further,
The contact area between the side surface of the rotary drum and the radial / trust bearing is reduced, and even if the contact surface is worn out, the flange of the rotary drum and the support valve do not come into direct contact with each other. It is very effective in preventing noise and noise.
