An annular groove 56 formed on the outer circumferential surface of the rotary tube 55 and an annular groove 5 formed on the inner circumferential surface of the connection port 27 and overlapped with the annular groove 5G of the rotary tube 55.
An annular ring body 59 is provided between the rotary tube 55 and the connecting port 27 to prevent the rotary tube 55 from being removed from the connection port 27. Further, a short cylindrical seal backing 60 is embedded and fitted into the rear end of the outer circumferential surface of the rotary tube 55, and the outer circumferential surface of this seal backing 60 is
The WJ is freely and airtightly abutted against the inner circumferential surface of the connection port 27. Furthermore, a recess 61 having a locking hole (not shown) is formed on the inner circumferential surface side of the front end of the rotary tube 55.

On the other hand, an integral cover 63 with a built-in movable clamp 62 is attached to the outer peripheral surface of the connecting pipe portion 43 of the hose 41. 64 and the locking claw portion 65, and are urged outward by a spring (not shown). Further, the diameter of the illustrated short portion of the connecting pipe portion 43 of the hose 41 is tapered toward the rear.

Then, during cleaning, the hose 41 is connected to the vacuum cleaner main body 1 by fitting the illustrated rear end of the connection pipe portion 43 of the hose 41 into the rotating pipe 55 of the connection port 27 of the vacuum cleaner main body 1.
Detachably connect to. That is, as the connecting pipe portion 43 is fitted into the rotating tube 55, the rear end portion of the cover unit 63 is fitted into the recess 61 of the rotating tube 55, and the clamp biased by the spring The locking claw portion 65 of 62 is inserted into the locking hole of the rotating tube 55 through a reciprocating motion, and the hose 41 is held in the connected state. Note that the hose 41 is attached to the vacuum cleaner body 1.
To release the clamp, push the operating part 64 of the clamp 62 to remove the locking claw part 65 from the locking hole of the rotation tube 55, and then,
The connecting pipe portion 43 of the hose 41 is handled through the rotating pipe 55.

According to this structure, the connection pipe part 43 of the hose 41 is connected to the connection port part 27 of the cleaner main body 1 by the rotary pipe 5 which is rotatably provided.
5, the hose 41 also rotates in the circumferential direction with respect to the cleaner body 1, so when the suction port body is rotated on the surface to be cleaned during cleaning, By rotating the hose 41 in the circumferential direction, twisting of the flexible hose body 42 can be eliminated, and this hose body 42
It is possible to prevent damage to the product without applying excessive force to the product, and to clean the product with good operability.

In both of the above-mentioned embodiments, the connecting port body 26 having the connecting port portion 27 to which the connecting pipe portion 43 of the hose 41 is connected to the inclined surface 1G formed on the upper surface of the vacuum cleaner main body 1 is connected above and below. Although the structure in which the vacuum cleaner main body 1 is provided so as to be freely movable has been described, the upper surface of the vacuum cleaner main body 1 may be formed horizontally, and the connection port body 26 may be provided on this horizontal upper surface so as to be freely movable up and down. The connection port body 26 is installed on the vertical front surface of 1 so as to be movable up and down.

Furthermore, in both of the above embodiments, the connection port body 26 has a cylindrical shape, but the shape of the connection port body 26 is not limited to the cylindrical shape, and may be, for example, spherical.

Furthermore, in both of the above embodiments, the connection port body 2 of the vacuum cleaner main body 1
6 is movable up and down, so that the hose 41 can be moved up and down with respect to the vacuum cleaner body 1.
A connecting pipe connected to the connecting port 21 fixed to the connecting pipe, and an upper part as a rotating part with one end connected to the connecting pipe so as to be movable up and down, and a hose body 42 connected to the other end. The hose 41 may be made vertically movable by being configured with non-cooperating tubes.

(Effects of the Invention) According to the present invention, the connection port to the right of the connection port to which the hose is connected is rotatable in the vertical direction with respect to the vacuum cleaner body, so that the connection port to which the hose is connected can be freely rotated in the vertical direction. The vertical orientation of the connecting pipe part of the hose changes over a wide range, and therefore, the degree of freedom in the vertical position of the suction mortar connected to the hand grip part of the hose via an extension pipe increases, for example. , it is possible to easily and efficiently clean a wide range, especially in the vertical direction, from the floor surface to the top f/F surface.
