BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) As shown in FIGS. 1 and 2, a stick type and upright type (hereinafter referred to as stick type) electric vacuum cleaner A includes a cleaner body 11 and a cleaner body. The suction port body 12 is provided at the lower end of the cleaner body 11, and the main body handle portion 13 and the stick portion 14 are provided at the upper end portion of the cleaner body 11.

A dust collector 15 and an electric blower 16 for sucking air and dust from the suction port 12 are provided in the cleaner body 11.

The stick portion 14 is provided with a holding portion 17 for supporting an arm or an elbow, an operating switch 18, and an operating handle portion 19.

The hold portion 17 is made of, for example, a synthetic resin U.
The cushioning member 20 is formed in a letter shape and is an elastic body on the inner peripheral portion. The cushioning member 20 is, for example, a container made of various rubber such as urethane rubber or a soft plastic filled with air or the like. The cushioning material 20 is fixed to the inner peripheral portion of the hold portion 17 with an adhesive (not shown).

A method of using the above structure will be described.
When the user cleans the stepped surface D to be cleaned with the electric vacuum cleaner A, the user holds the main body handle 13 by hand and lifts the cleaner. And is supported by the main body handle portion 13 and the hold portion 17.

In this state, the weight when the vacuum cleaner shown in FIG. 4 is lifted can be supported by the hands, arms or elbows, so that the weight of the vacuum cleaner is not concentrated on the hands or wrists and the like. The burden on Therefore, it is possible to easily operate the electric vacuum cleaner A when cleaning the surface D to be cleaned having steps such as stairs.

In this case, the holding part 17 has a cushioning member 20.
Since it is attached, the elastic body can support the arm and elbow by softening it. (Second Embodiment) The same parts as those in the first embodiment described above are designated by the same reference numerals, and different parts will be described.

Further, the electric vacuum cleaner A has the following structure. As shown in FIGS. 2 and 4, the holding unit 1
7 is provided with a clamp portion 21 that engages the stick portion 14 that faces the cushioning member 20 by sandwiching it from the width direction. The clamp part 21 is attached to the stick part 1 by the clamp screw 22.
It is detachably attached by 4.

The hold portion 17 can be moved in the longitudinal direction of the stick portion 14 by loosening the clamp screw 22 (the moving direction is indicated by an arrow in FIG. 3). Therefore, the hold unit 17 can be arranged at a suitable position according to the length of the user's arm.

That is, the user uses the handle portion 13 for the main body.
The clamp screw 22 is loosened by moving the clamp part 21 with respect to the stick part 14 at an optimum distance between the holding part 17 and the hold part 17, and the clamp screw 22 is tightened to fix the hold part 17 to the stick part 14. .

Thus, the user can handle the main body handle portion 13
Is gripped by hand, and the arm or elbow is supported by the cushioning material 20 of the hold portion 17. Therefore, the suction port body 12 can be cleaned by lifting it from the floor surface F to the surface D to be cleaned having a step.

As described above, in the first embodiment, the distance between the main body handle portion 13 and the hold portion 17 can be adjusted according to the physique of the user so that the user can optimize the distance. The vacuum cleaner A can reduce the burden on the hands, wrists, etc. without concentrating the weight of the vacuum cleaner A on the hands, wrists, etc.
The operation of can be facilitated.

(Third Embodiment) As shown in FIGS. 5 to 8, in a canister-type electric vacuum cleaner A, a cleaner body 41 has a body case 42. An electric blower and a dust collector (not shown) are housed in the main body case 42.

A swingable swivel wheel 43 is attached to the center of the lower front side of the main body case 42, and rear wheel wheels 44, 44 (only one is shown) are rotatably attached to both rear side surfaces.
