There is provided a suction tool for a vacuum cleaner that can easily remove dust entangled around a rotating brush with a small force in a sanitary manner with clean hands without spreading dust. The suction tool includes dust removing meansfor removing dust adhering to a rotating brush, the dust removing meansincludes a first remover that has substantially the same shape as a troughbetween cleaning bodiesor between cleaning body holding portionsof the rotating brush, and is guided in an axial direction of the rotating brushwithin the trough

Suction tool for vacuum cleaner

A refrigerator which may allow vegetables kept more fresh by minimizing temperature fluctuations in a vegetable compartment. The refrigerator minimizes dehydration in food stored in the vegetable compartment, so that vegetables are kept fresh longer. The vegetable compartment is arranged so as to be surrounded by freezing temperatures, and cooled through radiation cooling without receiving blowing cool air thereto to minimize temperature fluctuations, so that vegetables may be keep more fresh. At the same time, the vegetable compartment is sealed so that convection does not occur thereby minimizing dehydration in food, so that food is allowed to be kept fresh longer. Furthermore, the refrigerator is provided with compartments whose temperatures may be set to freezing temperatures. The vegetable compartment is arranged so as to be surrounded by compartments whose temperatures are freezing temperatures via partition parts.
