Abstract 1. Field of the Invention A vacuum cleaner has a case including a dust chamber filtering dust included in air, an appliance chamber sucking the filtered air from the dust chamber and discharging the air through a discharge port, and a cord chamber storing a wound electrical cord. A fan motor assembly is installed inside the appliance chamber of the case for forcedly sucking the air inside the appliance chamber and discharging the air. An exhaust duct is installed between the fan motor assembly and the discharge port in the case and guiding the air discharged from the fan motor assembly to the discharge port, and a flowing passage is disposed between the dust chamber and the cord chamber so that the air is able to flow therein, whereby overheating of case and of the electrical cord can be prevented and the durability and reliability of the cleaner can be enhanced.
