A scraper (14) for rotary brush, wherein a plurality of scraping parts (23) are spirally provided on the peripheral surface of a shaft body (22a) and brought into point−contact with a rotary brush (13) to scrape off deposit adhered onto the rotary brush (13), whereby, since the contact between the scraping parts (23) and the rotary brush (13) is a point contact, the wear of the rotary brush (13) and a load on a mechanism for drivingly rotating the rotary brush (13) can be reduced, strictness for bringing the scraper (14) for rotary brush into uniform contact with the rotary brush (13) through the overall length can be relaxed, and the positional relation between the rotary brush (13) and the scraper (14) for rotary brush can be adjusted easily.
