The rotation of the cleaner body 1 around the axis while the cleaner body 1 is standing up is regulated by the contact.

Reference numeral 20 denotes an engaging portion formed on the back of the cleaner main body 1 of the connection pipe 17, and reference numeral 21 denotes a lower case 15 of the suction tool main body 1.
When cleaning a bed or furniture under a recess formed in a rear portion, the cleaner main body 1 is laid substantially horizontally on the suction tool main body 13 (full flat state). Engages with the concave portion 21 so that the rotation of the cleaner body 1 in the left-right direction is restricted.

Reference numeral 22 denotes an inclined portion continuously formed on the left and right of the concave portion 21. The connection is made when the cleaner main body 1 is rotated downward while the cleaner main body 1 is rotated left and right. Tube 17
The engaging portion 20 is guided along the inclined portion 22 to the concave portion 21 so that the cleaner main body 1 is directed to the front, and therefore, the cleaner main body 1 is tilted to the maximum from a rotated state. Even in this case, the lower corner of the cleaner body 1 does not come into contact with the floor surface, and the floor surface is not damaged.

With the above structure, when cleaning the bed or the lower part of the furniture, the engaging portion 20 is placed in a state where the cleaner main body 1 is laid substantially horizontally on the suction tool main body 13 (full flat state).
Engages with the concave portion 21 to restrict the rotation of the cleaner main body 1 in the left-right direction, so that the cleaner main body 1 rotates and its lower corner does not contact the floor surface, and the floor of the flooring or the like can be used. The surface can be prevented from being damaged.

Further, even when the cleaner main body 1 is turned down to the maximum from the rotated state, the engaging portion 20 of the connecting pipe 17 is guided to the concave portion 21 along the inclined portion 22 of the suction tool main body 13. In addition, the cleaner main body 1 is turned to the front, and the lower corner of the cleaner main body 1 does not contact the floor, so that the floor is not damaged.

In the above embodiment, the engaging portion 20 is connected to the connecting pipe.
17 and is configured to engage with the concave portion 21 of the suction tool main body 13, but the engaging portion is formed at the lower rear portion of the cleaner main body 1 and engages with the concave portion 21 when the cleaner main body 1 is tilted. Alternatively, the rotation of the cleaner body 1 in the circumferential direction may be restricted.

(Angle) may be rotatable.

[0026]

According to the first to third aspects of the present invention, when cleaning the bed or under the furniture, the cleaner main body is laid substantially horizontally on the suction tool main body. Because the left and right rotation of the cleaner body is regulated,
The lower corner portion of the cleaner body does not rotate and does not come into contact with the floor surface, so that it is possible to prevent the floor surface such as flooring from being damaged.

Further, according to the configuration of claim 4 of the present invention,
Even when the cleaner body is turned from the rotated state, the engagement protrusion of the connection pipe is guided along the inclined portion of the suction tool body into the recess and engages, so that the cleaner body is turned to the front and cleaned. The lower corner of the machine body does not touch the floor surface and does not damage the floor surface.
