<p><P>PROBLEM TO BE SOLVED: To provide a more convenient electric travel bag which self-travels only by pushing a button. <P>SOLUTION: Driving wheels 4 in the electric travel bag are connected to an electric motor 5 via a coupler 10 and are driven by the rotation of the motor. Start/stop of the electric motor 5 is performed by an electric switch provided near the grip at the upper part of the bag. The coupler 10 absorbs the shock acting on the wheel when the bag falls down or is handled, and prevents the damage of the electric motor and a motor shaft. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
