ROTARY CLEANER BODY AND SUCTION HEAD BODY OF VACUUM CLEANER

摘要

PROBLEM TO BE SOLVED: To provide a floor brush having a rotary brush securely cleaning a floor surface. SOLUTION: The outer periphery of a brush base 14 is provided with first recessed engagement portions 15 along the axial direction of the brush base 14. The first recessed engagement portion 15 is locked with the base end parts of scraping members 21 to protrude the scraping members 21 in the radial direction of the brush base 14. The outer periphery of the brush base 14 is provided with second recessed engagement portions 16 different from the first recessed engagement portions 15 along the axial direction of the brush base 14. The second recessed engagement portion 16 is locked with the base end parts of brush members 22 to protrude the brush members 22 in the radial direction of the brush base 14 so that the brush member has a protruding amount from the outer periphery of the brush base 14 smaller than that of the scraping member 21. The tip end part of the brush member 22 is prevented from sinking when making contact with the floor surface, and the scraping member 21 and the brush member 22 securely clean the floor surface.
