The said holding part C is formed in the carrying handle 5 formed in the connection part 4. As shown in FIG.

In this embodiment, as long as it can prevent the suction hose 3 from loosening and can also reduce it, it is not specifically limited about the structure, It can select suitably, for example, the lower part of the handle 5 A coupler 31 can be formed in the pair, and a pair of retaining protrusions 32 can be formed to hold the suction hose 3 in the coupler 31.

The inner wall surfaces of these engaging portions 31 and the retaining protrusions 32 are preferably in a semicircular arc shape approximately the same as the outer shape of the suction hose 3.

By such a semi-circular arc shape, a part of the suction hose 3 bent in a U-shape can be attached and detached to the engaging portion 31 smoothly with one touch by utilizing the elasticity of the retaining protrusion 32.

In this embodiment, since the suction hose holding means which consists of the engaging part and the holding part is provided in the handle of an accessory, the number of parts and a number of processes are reduced, and the increase of a production cost can be suppressed.

According to the present invention, the terminal can be prevented from being damaged by arranging the terminal in a position where it is difficult to receive the bending load applied to the connecting portion when the handle is held by the connecting portion and the cleaning main body is lifted up.

Further, according to the present invention, since the suction hose holding means keeps a part of the suction hose, the loosening of the suction hose in the stand storage body can be prevented, so that the compact stand storage can be performed.

Also, even in the room, the appearance looks slippery.

In particular, the present invention can prevent loosening of the suction hose and is effective in the case of storing the stand in a state in which the suction pipe is freely expanded and contracted.
