Is rotatably connected to the rear of the suction port 5.

As shown in FIG. 3, a downward recess 1c is formed at the rear end of the lower surface 1b of the cleaner body 1. An upward concave portion 1d is formed at the front end of the lower surface 1b of the cleaner body 1.

As shown in FIG. 2, the rotary pipe 4 for connecting the support pipe 2 and the suction port 5 has an upward convex portion for fitting into the downward concave portion 1c of the cleaner body 1. 4d is provided. Further, the support pipe 2 is provided with a clamp hook 10 which is a downward convex portion for fitting into the upward concave portion 1d of the cleaner body 1. The clamp hook 10 is provided to be vertically movable with respect to the support pipe 2. In the present embodiment, an example in which the upward convex portion 4d is provided on the rotary pipe 4 has been described. However, the present invention is not limited to this, and the convex portion 4d may Alternatively, it may be provided at an appropriate position of the suction port 5.

As shown in FIG. 5, the clamp hook 10 is formed by connecting a pair of connecting plates 10c between a release knob 10a and a claw 10b.

The pair of connecting plates 10c are formed by the compression coil spring 1
1 are arranged in parallel with the compression coil springs 11 so as to sandwich them from the direction perpendicular to the paper surface of FIG. The upper end of the compression coil spring 11 is in contact with a spring stopper 12 fixed to the support pipe 2. The spring stopper 12 is provided between the pair of connecting plates 10c.

The clamp hook 10 can move up and down inside the cover 13 fixed to the support pipe 2.

When the vacuum cleaner of the present embodiment is transformed into a state of use as an upright, first, as shown in FIG. Is fitted to the upward projection 4d.

Thereafter, the cleaner main body 1 is rotated with the fitting portion between the concave portion 1c and the convex portion 4d as a fulcrum, so that the upward concave portion 1d of the front end of the cleaner main body 1 is fixed to the clamp hook 10 of the support pipe 2. To fit.

In the present embodiment, as shown in FIG. 5, a slant surface 10d is formed in the claw portion 10b of the clamp hook 10 so as to be inclined upward as the distance from the support pipe 2 increases. Therefore, by simply rotating the cleaner main body 1 in the direction in which it contacts the support pipe 2, the edge 1f of the concave portion 1d of the cleaner main body 1 becomes inclined 10d.
Then, the clamp hook 10 is pushed up while contacting with the rim, and thereafter, when the entire claw portion 10b completely rides over the edge 1f, it falls into the concave portion 1d. As a result, the fitting between the concave portion 1d and the clamp hook 10 can be easily performed. In the present embodiment, an example having the slope 10d has been described, but the present invention is not limited to this. Even if the slope 10d is not provided, if the release knob 10a is manually operated up and down, The fitting between the concave portion 1d and the clamp hook 10 can be performed.

In the present embodiment, an example having the compression coil spring 11 has been described as an example of the urging means for urging the clamp hook 10 downward, but the present invention is not limited to this. Even if an elastic member such as rubber is used as another urging means, the fitting between the concave portion 1d and the clamp hook 10 can be further strengthened. Note that the fitting between the concave portion 1d and the clamp hook 10 can be performed only by the falling of the clamp hook 10 due to its own weight without having the urging means.

Next, when the cleaner body 1 is to be detached from the support pipe 2, the release hook 10a of the clamp hook 10 is slid upward in the reverse procedure to pull out the clamp hook 10 from the recess 1d. In the same manner, it can be removed in the reverse order. Therefore, the recess 1
Since the fitting and the separation between c and the convex portion 4d and between the concave portion 1d and the clamp hook 10 can be sequentially performed one by one, the attachment and detachment of the cleaner body 1 can be easily performed. .

When the main body 1 is detached from the support pipe 2, if the clamp hook 10 is pushed upward, the main body 1 of the rear end portion of the concave portion 1c fitted with the upward convex portion 4d is formed. With the position as a fulcrum, it is likely to fall in a direction away from the support pipe 2. However, in the present embodiment, as shown in FIG. 1, a hose retainer 14 for fixing the hose 6 connecting the cleaner body 1 and the support pipe 2 to the support pipe 2 is provided by a clamp hook 10. Since the hose 6 is disposed at the upper position, the hose 6 is fixed to the support pipe 2 by the hose retainer 14, so that the cleaner main body 1 can be prevented from tipping over using the tension of the hose 6.

As shown in FIG. 8, in the vacuum cleaner according to the present embodiment, the hose 6 is connected to the cleaner body and the support pipe 2 with respect to the left and right when viewed from the front of the vacuum cleaner of FIG. Since it is symmetrically extended, there is no difference in ease of use between a right-handed person and a left-handed person.
