PROBLEM TO BE SOLVED: To easily and securely engage wiping fabric with a cleaning head. SOLUTION: Engaging parts 13 are provided on the cleaning head so that the wiping fabric is pushed inside and removably engaged. Linear slits 15-20 are circumferentially arranged with spaces therebetween on the engaging part 13 so as to extend from a general center part of the engaging part 13 to a circumferential part. In the general center part of the engaging part 13, one end of each of the slits 15, 16, 18 and 19 contacts with each of adjacent slits 15-20 so that a position of a point of contact of each of the adjacent slits 15-20 is different, and that a zigzag part 31 is formed by center-side end parts of the slits 15, 16, 18 and 20 in the general center part of the engaging part 13. Elastic tongue pieces 21-26 are formed between the adjacent slits 15-20 on the engaging part 13 so that the tongue pieces are elastically deformed inward and outward direction of the cleaning head.
