PROBLEM TO BE SOLVED: To hold back labor cost by eliminating the need for periodical cleaning work for higher cleanliness. SOLUTION: A belt-shaped seat skin 12 linked by a fastener 13 is arranged so as to be looped endless between rollers 8 and 9 and a drive roller 10 and fed in the direction indicated by the arrow B by the driving of a motor 11. The seat skin 12 is so arranged to prevent the generation of wrinkle by a tension applied by a tension adjusting mechanism 14. The feeding of the seat skin 12 can be constrained selectively by a lock mechanism 17. During the feeding of the seat skin 12, a part sterilized by a sterilization lamp 20 on the seat skin 12 is positioned anew at a point corresponding to a sitting surface. |
