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.
