<p><P>PROBLEM TO BE SOLVED: To establish the contact of a receiving electrode of an on-floor object with a transmission electrodes arranged on a floor, to surely establish the connection and separation of the receiving electrode to and from the transmission electrode, and to prevent the complication of the structure of the on-floor object. <P>SOLUTION: This collector wheel 13 is installed to the on-floor object 10 that self-travels on the power feeding floor with a plurality of the transmission electrodes arranged on the floor connected to underfloor wiring. The collector wheel comprises transmission function parts 19 each of which is constituted of a circular frame 14 arranged with a plurality of the receiving electrodes 16 on grounding surfaces 15 that are external peripheral faces having friction resistance not causing an unnecessary slide between the floor and the receiving electrodes, and a wheel 17 rotatably assembled to a wheel shaft 18 immovably fixed to a vehicle body 11, contains an in-wheel motor 20 composed of a rotor fixed to the wheel 17 and a stator fixed to the wheel shaft 18 so as to face the rotor, and performs the transmission and reception of a signal including power between the vehicle body 11 and the collector wheel. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
