|発明の名称||GROUND BRUSH DEVICE|
PROBLEM TO BE SOLVED: To provide a ground brush device, which is arranged so that the rolling-in part of a flat spring for pressurizing a brush does not fly out in a direction opposite to the rolling-in direction with the vibration from a wheel and where a stopper for preventing overinsertion of the flat spring and a bolt attached to a journal box do not interfere with each other, and which can be attached even to a small mounting space.
SOLUTION: In the ground brush device, where a brush 2 is installed in the brush insertion groove of a brush holding box 1, and the mounted brush 2 is pressurized with the flat spring 10 having a spiral part so as to bring it into contact with a spring 15 attached to the wheel, a pair of sidewalls 23 projected sideways are provided a terminal 22 for fixing a lead wire 8 so that the spiral part of the spring hooks on the sidewall 23, thereby preventing the flat spring 10 from easily flying out of the head of the brush by vibration.
