PROBLEM TO BE SOLVED: 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. SOLUTION: The bending extension pipe of the vacuum cleaner comprises a first extension pipe, a second extension pipe turnably connected to the first extension pipe, and a release handle for selectively locking the first or second extension pipe. When the user holds the release handle, the lock of the first or second extension pipe is released. COPYRIGHT: (C)2005,JPO&NCIPI
