As shown in FIG. 6, an end of a rotating member 8 described later is formed by insert molding or a rotating member 8. The end is inserted into a groove formed in the wheel 7 and integrated with an adhesive, so that the rotating member 8 rotates as the wheel 7 rotates.

Reference numeral 8 denotes a net-shaped rotating member loosely fitted to the outer periphery of the cylindrical body 3 of the suction tool main body 1, which has a large frictional resistance with a surface to be cleaned, such as a synthetic resin such as polypropylene or polyethylene, or rubber, and is flexible. The rotating member 8 abuts on the rib 6 of the cylindrical body 3 in a state of being loosely fitted to the outer circumference of the cylindrical body 3 so as to maintain a gap between the rotating member 8 and the outer circumference of the cylindrical body 3. Reference numeral 9 denotes a plurality of openings formed in the rotating member 8, which are formed so as to communicate with the intake port 5 formed in a lower portion of the outer periphery of the cylindrical body 3 of the suction tool main body 1.

Thus, the connection pipe 2 is connected to a vacuum cleaner (not shown) to clean a surface to be cleaned such as a futon. Suction tool body 1
Is moved in the front-rear direction, the wheel 7 and the rotating member 8 come into contact with the surface to be cleaned.
The wheel 7 and the rotating member 8 rotate with the movement of the suction tool main body 1. Since the rotating member 8 rotates in contact with the annular rib 6 formed from the suction tool main body 1, frictional resistance with the suction tool main body 1 can be reduced, and the mobility of the suction tool main body 1 is improved. Can be. Since the suction device main body 1 pivotally supports the wheels 7 and the rotating members 8 on both sides independently and rotatably, it is easy to change the moving direction even when changing the moving direction of the suction device main body 1. Can be. Further, since the wheel 7 is formed to have a larger diameter than the rotating member 8 and the end of the rotating member 8 is covered by the wheel 7, it is possible to prevent the end of the rotating member 8 from being caught on the surface to be cleaned and impairing the mobility. can do.

The suction tool main body 1 is operated by the suction force of the vacuum cleaner.
Although dust and the like adhering to the surface to be cleaned are sucked from an intake port 5 formed in the lower part of the outer periphery of the cylindrical body 3, the rib 6 keeps a space between the outer periphery of the cylindrical body 3 and the rotating member 8. The surface to be cleaned is drawn by the suction port 5
And a good dust-absorbing function can be maintained.

Further, since the rotation member 8 has an opening 9 communicating with the suction port 5 of the suction tool main body 1, the suction port 4 and the opening 9 of the suction tool main body 1 are rotated as the rotation member 8 rotates. The relatively large dust such as hair and lint can be reliably sucked at the position where the.

Further, since a plurality of intake ports 4 are formed in the lower part of the outer periphery of the connection pipe 2 of the suction tool main body 1, dust can be sucked in the entire lower part of the suction tool main body 1, and uneven cleaning may occur. Absent.

In this embodiment, the ribs 6 are formed in an annular shape on the outer periphery of the cylindrical body 3 of the suction device main body 1. However, as shown in FIG. Good. With this configuration, it is possible to maintain the space between the cylindrical body 3 of the suction tool main body 1 and the rotating member 8 and reduce the frictional resistance between the suction tool main body 1 and the cylindrical body 3. Further, as shown in FIG. 8, the rib 6 may be formed integrally with the rotating member 8 in a ring shape.

Further, as shown in FIG. 9, the end of the rotating member 8 may be integrated with the outer periphery of the wheel 7 by welding or bonding, or as shown in FIG. 10, the wheel and the rotating member 8 may be integrally formed. .
