Abstract
To prevent a switch of an electric vacuum cleaner from breakage even when an excessive load is applied to an operational piece supported slidably on the body of the cleaner, by furnishing a blower controlling switch to be turned on and off from the operational piece in a switch mounting part through a resilient mounting plate. An operational piece in the form of pedal 15 is installed in such a way as enclosing a switch mounting part 6 formed in the rear top of the upper case 3 of the body of an electric vacuum cleaner. When the pedal 15 is operated, for example stamped by foot, its undersurface on the free end side runs against the upper case 3 so that it is hindered from rotating downward. In case the stamping force is large, the pedal 15 makes elastic deformation to cause increase in the switch 10 pushing force by the operating part 19, but this pushing force causes elastic deformation of the mounting plate 9 to prevent the switch 10 from breakage. When the deformation of the plate 9 enlarges, the force applied to the switch 10 through a supporting projection 8 is transmitted to a recess 7, and its elastic deformation precludes the switch 10 from breakage.
