摘要： A portable electric vacuum cleaner according to the present invention includes a body (23), and a suction nozzle (27) provided unitarily with the body (23) at a front lower portion of the body (23) and projecting forward from the body (23) as having a predetermined length. The suction nozzle (27) is, for example, a tubular member of a fixed shape composed of a resin and tapered toward a distal end thereof. The suction nozzle (27) has a nozzle suction port (271) provided at the distal end thereof. The portable electric vacuum cleaner is generally used with a floor brush (3) attached to the suction nozzle (27). When the floor brush (3) is detached from the body (2), the suction nozzle (27) appears. Thus, the portable electric vacuum cleaner is conveniently used. Further, the suction nozzle (27) is hardly missing.
