Since a receiving part 36 to be engaged to the sliding part 37 of the running wheels 3 and to position the running wheels 33 is formed integrally with the bearing 35, the running wheels 33 and the follower wheels 41 are coaxially positioned and, since a distance from the outer peripheral face of the running wheels 33 to a floor 17 to be cleaned and a distance from the outer peripheral face of the follower wheels 41 to the floor 17 do not change the relation when the floor 17 is pressed with a main body 11 of the sucking port, the running wheels 33 do not touch the floor 17 such as a wooden floor or the like so as to prevent the operability of the nozzle body 11 of the sucking port from being lowered or the floor 17 from being damaged.
