Provided is a nozzle for a vacuum cleaner. The nozzle for the vacuum cleaner includes a nozzle body defining an outer appearance thereof, a vibration member disposed in the nozzle body, the vibration member separating foreign substances from a surface to be cleaned, a driving motor providing a driving force to the vibration member, and a power transmission unit configured to convert a rotation movement of the driving motor into a linear movement of the vibration member. The vibration member repeatedly strikes the surface to be cleaned by the driving force of the driving motor. The nozzle for the vacuum is advantageous in that it can easily suck dusts scattered during cleaning.
