Abstract

A vacuum cleaner includes working elements of cleaner, that is, a blower and a dust collection unit disposed in a nozzle section of which casing is composed of an upper unit and a lower unit, and having a handle coupled to the nozzle section. At least one of the working elements is supported by the upper unit and a support unit provided in the lower unit or by the lower unit and a support unit provided in the upper unit. Therefore, the cleaner can be repaired without having all screws removed, thus repaired conveniently.

Claims
