Claims (1)

[Scope of Claim for Utility Model Registration] 1. A motor storage case 12 that is attached and integrated with the tip of the handle tube 11, and a DC motor 14 that is built into the storage case 12 and is also exposed to the front from the storage case 12. A rotating brush 21 is transmission-coupled to the output shaft 19 of the motor 14 via the universal joint shaft 18.
, a swing angle regulating plate 22 that integrally projects forward from the motor housing case 12 as a pair of left and right opposite positions sandwiching the universal joint shaft 18; and a bending fulcrum X- of the universal joint shaft 18.
A bearing sheath ring 25 that can be bent integrally with the universal joint shaft 18 by being fitted into the sleeve in a non-rotatably loose state at a position closer to the tip than X.
and an engagement flange 25b projecting from the bearing sheath ring 25.
and a bellows 26 that is connected and tensioned so as to cover the swing angle regulating plate 22 between the front and rear of the motor housing case 12, and is formed at the tip of both swing angle regulating plates 22. By engaging and supporting the engagement flange 25b of the bearing sheath ring 25 on the arcuate guide surface 22a, rotation is possible integrally with the universal joint shaft 18 within the angular range β defined by the guide surface 22a. A hand-held electric vacuum cleaner characterized in that a brush 21 is set to be adjustable in a swinging state in the vertical direction. 2. A motor storage case 12 that is attached and integrated with the tip of the handle tube 11, a DC motor 14 built into the storage case 12, and an output shaft 19 of the motor 14 that is also exposed forward from the storage case 12. Rotating brush 21 transmission-coupled via universal joint shaft 18
, a swing angle regulating plate 22 that integrally projects forward from the motor housing case 12 as a pair of left and right opposite positions sandwiching the universal joint shaft 18; and a bending fulcrum X- of the universal joint shaft 18.
A bearing sheath ring 25 that can be bent integrally with the universal joint shaft 18 by being fitted into the sleeve in a non-rotatably loose state at a position closer to the tip than X.
, a passive board 29 attached and fixed to the bearing opening cylinder part 25a of the bearing sheath ring 25 in parallel with the swing angle regulating plate 22; The movable plate 33 is rotatably operated around a support shaft 36 which is parallel to the bending fulcrum X-X of the universal joint shaft 18 so that The Bowden wire 32 is wrapped around and locked, and the engagement flange 25b protrudes from the bearing sheath ring 25.
and a bellows 26 connected and suspended between the front and rear of the motor housing case 12 so as to cover the swing angle regulating plate 22 and the passive board 29, and the tip portions of both swing angle regulating plates 22. The engaging flange 25b of the bearing sheath ring 25 is engaged with and supported by the arcuate guide surface 22a formed on the movable plate 33.
By rotating it with the swing operation lever 38 and pulling the Bowden wire 32, the rotating brush 21 can be rotated integrally with the universal joint shaft 18 within the angular range β defined by the guide surface 22a. A hand-held electric vacuum cleaner characterized in that the handle tube 11 can be adjusted to swing vertically from the hand portion thereof. 3. The handle tube 11 is an assembly consisting of a thick main body tube section 11a and a thin extensible tube section 11b fitted to the main body tube section 11a so as to be able to extend and contract freely, and the operation is fixed and integrated with the hand section of the main body tube section 11a. To the block 34, the spindle 3 of that block 34
6 is built-in, and the adjustment plate 33 is set so that it can be rotated from the outside of the main body tube portion 22a by a swing operation lever 38 attached and fixed thereto. A hand-held electric vacuum cleaner according to claim 2.
