摘要： A nozzle unit for an electric vacuum cleaner has a body case with a nozzle open toward a surface to be cleaned, a first pipe coupled to the body case so as to be rotatable in the direction, and a second pipe coupled to the first pipe so as to be rotatable in the direction. A first and a second air flow passage, formed inside the first and second pipes respectively, are arranged substantially in a straight line as seen in a side view. The first pipe has a sliding portion that has an arc-shaped cross section and that slides along the inner surface of the body case, and this sliding portion is arranged inside the body case, which is substantially rectangular, as seen in a plan view.

摘要： A nozzle unit for an electric vacuum cleaner has a body case 32 with a nozzle 34a open toward a surface to be cleaned, a first pipe 35 coupled to the body case 32 so as to be rotatable in the direction J1, and a second pipe 36 coupled to the first pipe 35 so as to be rotatable in the direction J2. A first and a second air flow passage, formed inside the first and second pipes 35 and 36 respectively, are arranged substantially in a straight line as seen in a side view. The first pipe 35 has a sliding portion 35a that has an arc-shaped cross section and that slides along the inner surface of the body case 32, and this sliding portion 35a is arranged inside the body case 32, which is substantially rectangular, as seen in a plan view.

摘要： An electric vacuum cleaner has a main body incorporating an electric blower, a nozzle unit having a nozzle, and a first and a second connection pipe fitted between the main body and the nozzle unit so as to serve as part of the passage for a dust suction air flow generated by driving the electric blower. The first and second connection pipes are rotatable, and support the main body in a standing position.
