Abstract

PURPOSE:To provide a vacuum cleaner in which a housing space is procured and cleaning noise is reduced, and whose size is minimized. CONSTITUTION:At a time of cleaning, an electromotive fan 26 is driven to collect dust suctioned through a hose in a dust collecting bag 16, and air is exhausted through a body exhaust port 34 and a cover exhaust port 84. At a time of exhaustion, the air, getting out of the body exhaust port 84 and passing through a space in a cover 81, is exhausted out of the cover exhaust port 84 of a cover 81. Thereby noise of the electromotive fan 26 leaking outside can be reduced. In the case that a cleaner body 1 is mount on the rear part when it is not used, the cover 81 works also as a part of a mount surface 93. Inside the cover 81, a rib part 87 which is made vertical to a mount surface part 92 of the mounting surface 93 is formed, so that a rear part of an upper body case member 5 is brought into contact with a tip end of a rib part 87 so as to increase strength enough not to injure the cover 81. In a part surrounded by the rib pat 87, an accessory housing part is formed to house a pick, whereby space is utilized efficiently and the size of a cleaner is minimized.
