Abstract
A current collector includes the following members. A frame is mounted at its base end on a movable body. A current collector shoe assembly is mounted on a top end of the frame and is brought into contact with a feeder. A first spring applies a spring force to the frame so as to urge the top end of the frame toward the feeder. A second spring is arranged between the frame and the current collector shoe assembly for pressing the current collector shoe assembly to the feeder. A damper applies a damping force to the vibration of the current collector shoe assembly.
