To provide a bending extension pipe of a vacuum cleaner with the improved structure for a user to easily perform the cleaning work by bending an extension pipe with simple operation of a button without bending the user's body or lowering the posture.
An air-tight channel is formed in the extension pipe between a cleaner body and a suction brush, and the body of the extension pipe can be bent according to the selection by the user. The extension pipe comprises a first extension pipe, a second extension pipe rotatably connected to the first extension pipe, and a locking projection elastically deformable by the sliding motion, mounted in the first extension pipe to be selectively stored in one of a plurality of locker holes formed in the second extension pipe. The extension pipe also has an elastic locker for restraining the turning of the first and second extension pipes and a joint cover body, which is connected to the second extension pipe so that the connection part of the first and second extension pipes can be sealed air-tightly and is turnable together with the second extension pipe.
