PROBLEM TO BE SOLVED: To provide a floor brush provided with a rotary brush, the productivity of which is increased. SOLUTION: A shaft 32 projecting from both ends of a brush base 14 in an axial direction is concentrically fixed with the brush base 14. Fixing parts 33 are provided on both ends of the shaft 32. A retaining hole 42 is provided on a holding plate 41 for locking the holding plate 41 against the shaft 32 by a fit of the fixing part 33 into the hole 42. Only press-fitting the fixing part 33 into the hole 42 easily locks the holding plate 41 against the shaft 32, increasing the productivity. COPYRIGHT: (C)2005,JPO&NCIPI
