PROBLEM TO BE SOLVED: To provide a supporting structure of rotary body in a rotary disinfecting and sterilizing device that can automatically adjust and control the rotary body's movement in the axial direction within a scope of safe rota tion with a rather simple composition without settling a correctional structure separately. SOLUTION: The rotary disinfecting and sterilizing machine consists of a sealed package 1, plural supporting rollers 3, which support rotary body 2 in the sealed package in contact with plural places on the outer surface of the rotary body 2 as it can turn around, and a drive of the rotary body 2. The machine consists of at least two ring-shaped contacting parts 6 and 7 on the outer surface around the rotary body 2 as they contact with the supporting roller 3. The part to come come into contact with the ring-shaped contacting part 6 and 7 and with the supporting rollers 3 is shaped as the length (diameter) of its circumference serially increases or decreases in accordance with the contacting points' movement toward the direction of the axis and also the changing state about the length of the circumference (diameter) should be reversed at the ring-shaped contacting parts 6 and 7. |
