摘要： PURPOSE:To improve workability of a cleaner main body at the time of cleaning, and to make it convenient for carrying and containment at the time of containing it by detaining the main body to a cord coiling device so as to be freely attachable and detachable. CONSTITUTION:A main body 1 is separated from a cord coiling device 3, and at the time of cleaning, the cord coiling device 3 is fixed in a prescribed position, and only the main body 1 is moved. Also, when the main body 1 is placed on the upper face of the cord coiling device 3, a tapered part 23a of a hook 23 is pushed by a projection 22 due to its weight and inclined to the inside, the projection 22 is engaged to an engaging part 23b the hook, and the main body 1 is detained to the cord coiling device 3. In the case of detaching it, the detainment is released by pushing a release button 25. When a coiling button 26 releases the pressing, an output cord 29 can be drawn out freely. Also, when cleaning is finished and the bottom face of the main body 1 is fitted to a projectingly provided part 3a on the upper face of the cord coiling device 3 and placed thereon, since the bottom face 1a of the main body presses down the coiling button 26, the output cord 29 is coiled automatically into the cord coiling device 3.

摘要： PURPOSE:To prevent the damage of a stopper, and also, to miniaturize the cleaner main body by forming a shape of the stopper like a trough, and as a result, constituting a containing part of a cleaner attachment by utilizing a margin space formed in the upper part of the stopper. CONSTITUTION:A stopper 20 of the vacuum cleaner is formed like a semicircular trough. Also, by utilizing a space formed newly on the upper face of its trough, an attachment containing part 21 for containing a clearance nozzle, etc., of the cleaner is provided. Since the stopper 20 is formed semicircularly, its mechanical strength is large, and it is not damaged by the degree of pressure of the upper cover 2. Also, since the stopper 20 is formed like a trough, the attachment containing part 21 is constituted by utilizing a margin space formed in the upper part of the stopper, and an attachment such as a clearance nozzle, etc., is contained therein, therefore, length L2 of the part of a rear part air course 10 of the cleaner main body 1 can be made small.

摘要： PURPOSE:To enlarge an output control width and to suppress an operation noise by insertably arranging a resistor having a resistance value equal to or above a variable resistance value in series to the variable resistance of a hand switch in a power controller circuit. CONSTITUTION:By changing the resistance value of a variable resistance 4 of the circuit of a power controller 5, an output is changeable. In the power controller circuit, a resistor 11 having the resistance value equal to or above the resistance value of the variable resistance 4 is provided insertably in series on the variable resistance 4. Namely, when a large output is required, the resistor 11 is short-circuited, and simultaneously, when the operation in executed with a low output in order to suppress the operation noise, since the resistor 11 can be inserted into the circuit, the low output, in which the operation noise is small can be used at a night when the restriction of the noise is strict. Consequently, the width of the output control can be enlarged, and simultaneously, the title cleaner can be used even at a place where a noise regulation is strict.
