ての車輪台１１の回転は略３６０°に規制されている。A description will be given below with reference to FIGS. 6 and 7. Reference numeral 1 denotes an electric vacuum cleaner body (hereinafter referred to as a main body) in which a dust collecting chamber, a motor (not shown), and the like are arranged. Reference numeral 2 is an intake port provided in the main body 1 in front of the dust collection chamber, and is connected to the connection pipe 4 of the hose 3. An extension pipe 6 is connected to the tip pipe 5 of the hose 3, and a floor nozzle 7 is provided at the tip of the extension pipe 6.
Are connected. A wheel stand 11 is provided on the lower surface of the main body 1 so that casters 8 project from the main body 1 in four directions, and are rotatably arranged via a rotary shaft 9 formed on the main body 1 and by a roller 10. Is equipped with. Further, the rotation of the wheel base 11 with respect to the body 1 is restricted to about 360 ° by the stopper A1a formed on the lower surface of the body 1 and the stopper B11a formed on the surface of the wheel base 11 on which the body 1 is arranged.

た。However, in the above structure, when the main body 1 is rotated on the wheel stand 11, the rotatability is good, but for example, the main body 1 is rotated around and the stopper A1a and the stopper B11a are rotated. In the contacting state, the rotatability of the main body 1 becomes very poor. Further, the fact that the main body 1 and the wheel stand 11 are configured to be rotatable means that a gap is formed between the main body 1 and the wheel stand 11, dust is accumulated in the gap, and a match stick or a toothpick is used. When such a substance enters, the rotatability of the main body 1 will be significantly reduced. In addition, a separate member called a wheel stand 11 is used, and the roller 1 is used to rotate the main body 1 with respect to the wheel stand 11.
0 is required, the structure is complicated, workability is poor, and the cost is increased.
The weight is getting heavier. Further, the rotating shaft 9 formed on the main body 1 is always subjected to a force, and the stopper A1a and the stopper B11a further collide with each other in the use state, and there is a problem in each strength and durability.

してある。(Embodiment 1) In the first technical means, as shown in FIGS. 1 to 3, 21 is a dust collecting chamber 22 having an upward opening formed on the front side, and a motor 23 for sucking dust on the rear side. , A body incorporating a cord winding device 25 around which a power cord 24 is wound, a paper bag 26 accumulating dust is detachably attached to the dust collection chamber 22, and a lid 27 is provided so as to cover the upper opening thereof. Is rotatably arranged on the main body 21. An intake port 30 to which a connecting pipe 29 of the hose 28 is attached is formed in the lid 27, and the tip pipe 3 of the hose 28 is formed.
An extension pipe 32 is attached to 1, and a floor nozzle 33 is attached to the end thereof. The casters 35 are arranged on the four sides of the lower surface 34 of the main body so as not to protrude from the outer shape of the main body 21, and are located substantially at the center of the caster 35 from the lower surface of the caster 35.
A roller (fulcrum) 36 is arranged so as to project downward by one.

L is lower than the lower surface of the caster 35 on the rear side of the lower surface 34 of the main body 21.
The roller 38 is arranged so as to be located only 5 above.
As a result, when the hose 28 is suddenly pulled, the front portion of the main body 21 floats and the roller 38 comes into contact with the floor surface, and the main body 21
And the rollers 38 disposed on both sides of the rear of the main body 21 are supported, so that the main body 21 can be moved smoothly. Further, even when performing the upward cleaning, by pulling the hose 28 upward, the front portion of the main body 21 floats and the roller 38 is grounded on the floor surface, and the two-point support of the roller 38 facilitates the upward cleaning of a wide range. It can be done.
