[Means for solving problems]
The electric vacuum cleaner according to claim 1 of the present invention is at least one end side of a bellows-shaped flexible hose that mechanically and electrically connects between the vacuum cleaner main body and an attachment such as a suction port with a built-in electric brush. Is composed of a bellows connecting pipe and a connecting pipe that is externally fitted to the bellows connecting pipe, and the electrical connection between them is connected using a plurality of flexible lead wires, and the bellows connecting pipe is connected. It is an electric vacuum machine provided with means for regulating the relative rotation range with the outer fitting connection pipe, and the bellows connecting pipe has an annular storage portion for accommodating the lead wire on the outer periphery thereof and a bellows of the annular storage portion. Notches for lead wire lead- in are provided at equal intervals in the circumferential direction on the side side wall, and the plurality of lead wires are passed through the notches, and the lead-in positions into the annular storage portion are different. The wire is provided with a slack portion in the annular storage portion that allows relative rotation between the bellows connection pipe and the outer fitting connection pipe, and the outer fitting connection pipe is provided with a circumferential direction at a position facing the annular storage portion of the bellows connection pipe. Holes for drawing out corresponding to each lead wire at equal intervals, a lid covering these holes , and a lid connected to each lead wire in the space covered by these lids, and the tip protrudes outward. It is provided with a terminal.

0014.
Further, in the vacuum cleaner according to claim 2, the sizes of the holes for pulling out the lead wires provided in the outer fitting connection pipe are different .

0031
Further, according to the second aspect of the present invention, since the sizes of the holes for pulling out the lead wires provided in the outer fitting connection pipe are different , erroneous wiring can be prevented and the assembling property is improved.

Claims (2)

At least one end side of a bellows-like flexible hose that mechanically and electrically connects between the vacuum cleaner body and an attachment such as a suction port built in an electric brush, the bellows connection pipe and this can be rotated relative to this. Consists of an externally fitting connection pipe and connecting the electrical connection between them using a plurality of flexible leads and restricting the relative rotation range between the bellows connection pipe and the externally fitting connection pipe A vacuum cleaner provided with means,
Wherein the bellows connection pipe, an annular housing portion for accommodating the lead wires on the outer periphery, respectively provided notches for lead-lead in a location having equal intervals in the circumferential direction of the bellows side wall of the annular housing portion Passing the plurality of lead wires through the notched portion to make the lead-in position in the annular storage portion different;
Each of the lead wires is provided with a slack portion for permitting relative rotation between the bellows connection pipe and the externally fitted connection pipe in the annular storage portion.
In the outer fitting connection pipe, a hole for the drawer corresponding to the respective lead wires at a location having equal intervals in the circumferential direction at a position opposed to the annular housing portion of the bellows connecting pipe, a lid covering the hole, A vacuum cleaner comprising: terminals connected to the respective lead wires in the space covered by the lid and the tips of which are projected outward. The electric vacuum cleaner according to claim 1, wherein the size of each lead wire drawing hole provided in the externally fitted connection pipe is made different .
