Abstract
A telescopic pipe for an electronic apparatus is provided. The telescopic pipe for the electronic apparatus includes an outer pipe, an inner pipe with fixing grooves, inserted into the outer pipe; a holder pipe fixed to one side of the outer pipe, a handle pipe formed to surround the holder pipe, and a sealing member formed on an outer surface of the inner pipe to seal the space between the outer and inner pipes. In the telescopic pipe, the sealing member has at least one sealing portion of which a shape is changed by a negative pressure produced in the interior of the inner pipe so that its sealing force is enhanced.
