PROBLEM TO BE SOLVED: To prevent the main battery potential from leaking out to the body frame of car by connecting the body frame electrically with an axle through a brush and a spring and connecting the axle electrically with a conductive tire through a wheel. SOLUTION: A spring 821 is connected electrically with an axle 812 and a brush 822 is held by a conductive brush holder 823 secured to the lower end part of a suspension 814. Body frame 100 of car is connected electrically with the brush 822 by means of a connecting wire 824 through the brush holder 823. Contact face 810a between a conductive tire 810 and a wheel 813 is widened and a metal conductor 810b is connected electrically with the wheel 813. The wheel 813 is coupled with the axle 812 through a bolt 813a and connected electrically therewith. According to the structure, the body frame 100 has a potential identical to that of the earth 9. |
