  • An internal space of the main body 10 is divided by a partition 10d into a dust collecting chamber 10b in which the dust collecting unit 30 is installed and a suction chamber 10c in which the blower unit 20 is installed.
  • the partition 10d comprises an introducing hole 10e through which air from which the foreign matter has been filtered out by the dust collecting unit 30 is introduced.
  • the dust collecting unit 30 comprises a dust bag 31 having an open end connected with the connection hose 12 and an auxiliary filter 32 to cover the introducing hole 10e and to filter air, from which dust is primarily filtered by the dust bag 31.
  • the blower unit 20 comprises a blower fan 21 to generate the suction force and the blowing force, a motor 22 to rotate the blower fan 21, and a blower unit case 23 to accommodate the blower fan 21 and the motor 22.
  • the blower unit case 23 is divided into a fan accommodating part 23a to accommodate the blower fan 21 and a cylindrical motor accommodating part 23b to accommodate the motor 22.
  • the blower unit 20 employed in the vacuum cleaner of the present invention, is structured such that air discharged from the blower fan 21 passes through the motor accommodating part 23b and cools the motor 22 installed in the motor accommodating part 23b.
