Electric vacuum cleaner
First Claim
1. An electric vacuum cleaner comprising an electric blower, a nozzle unit having a nozzle, and a dust suction duct fitted between the electric blower and the nozzle unit so as to serve as a passage for a dust suction air flow generated by driving the electric blower,wherein the dust suction duct is rigid and bendable at a point along itself and can stand in an upright position by itself when secured to the nozzle, wherein the dust suction duct has a first dust suction duct of which one end is joined to the nozzle unit and a second dust suction duct is rotatably joined to another end of the first dust suction duct.
