PROBLEM TO BE SOLVED: To reduce the wear of collector pins or a power feeding plate for feeding power to a runner, to relieve workloads related to the inspection of the state of wear of the collector pins, to reduce the frequency of replacement of the collector pins, etc., or to prevent malfunction caused by the wear of the power feeding plate. SOLUTION: The game device 1 includes a running face 7s, the power feeding plate 6 laid within a surface parallel to the running face 7s, and the runner 40 to run on the running face 7s. The power collector 60 for receiving the power fed from the power feeding plate 6 with the collector pins 61 abutting to the power feeding plate 6 is mounted on the runner 40. A conductive rotor 64 is rotatably held in the front end of each power collector pin 61, and the power collector pins 61 are made to abut to the power feeding plate 6 by the rotors 64.
