PROBLEM TO BE SOLVED: To provide a brush for removing dirt, dust and trash adhering to an object, with improved reliability by preventing the brush from falling from a brush fitting part. SOLUTION: This brush 21 is formed by a pile 22 coming into contact with the object, a base 23 holding the pile 22, and a bucking agent 24 for preventing the pile 22 from slipping off the base 23. A brush bed 25 is formed by casting resin which is the same or substantially same material as that of the pile 22, the base 23 or the backing agent 24 in the base 23.
