2. Description of the Related Art Conventionally, a rotary brush for a floor suction tool is formed by extrusion molding as shown in Japanese Patent Publication No. 2-12567 (A47L 9/04) and Japanese Patent Publication No. 63-61014 (A47L 9/04). A brush-implanted portion is formed on the base, and a brush is implanted on the brush-implanted portion. However, this configuration has a disadvantage that the operation of implanting the brush is difficult, and the assembling workability is poor. Also, JP-A-2-82929 (A47L
As shown in 9/04), there is known a base in which a scrap made of a soft material is fixed to an extruded base. In this rotary brush, a scraping piece is mounted on a mounting portion formed on a base, but since the base of the scraping piece is inserted into the mounting portion from one end of the base, the workability of assembling is poor, and the rotating brush is rotated. When the brush is rotated at a high speed, the base of the scraping piece is deformed by the pressure applied to the scraping piece, the engagement between the base and the mounting portion is released, and the scraping piece may be peeled off.
