Claims

[Scope of utility model registration request]

An extension pipe 3 is connected between a floor suction port 2 equipped with an electric motor and a flexible pipe 1 connected to the vacuum cleaner body,
In the case where wiring 32 is provided from the flexible tube 1 side to the electric motor, the wiring 32 is provided through a wiring insertion passage 34 in the axial longitudinal direction provided in the extension tube 3, and the extension tube 3 and the extension tube 3 are connected to each other. A fitting cylinder part 15 is provided on one side of the connection part with the flexible tube 1 or the suction port 2, and is fitted into the other side from the axial direction, and from the button fitting hole 16 formed in the fitting cylinder part 15 in the radial direction. A push button 18 is provided which is biased to project outward and is removably fitted into a button fitting hole 57 formed on the other side, and a button pushing slope for pushing the push button 18 is provided on the other side edge. A surface 58 is provided, and a male connector 21 and a female connector 56 of the wiring 32, which are removably connected to each other, are provided on one end surface and the other end surface of the connecting portion, respectively, and the outer peripheral surface of the fitting cylindrical portion 15 or the corresponding An axial guide protrusion 47 is provided on either one of the inner circumferential surfaces on the insertion side.
are provided, and a male connector 21 and a female connector 5 are provided on the other side.
A guide recess is formed of a tapered guide recess 54 that relatively rotationally guides the guide protrusion 47 in the circumferential direction and a linear guide recess 55 that then guides the guide protrusion 47 in the axial direction so that the guide protrusion 47 and the guide protrusion 47 are aligned in the axial direction. 53. A connection structure for an extension pipe for a vacuum cleaner, characterized in that: 53 is provided.
