PURPOSE:To reduce the weight of the movable part of a current collector by providing a lever type arm separate from a current collecting arm having a current collecting shoe. CONSTITUTION:A lever type arm 7 separate from a current collecting arc 2 is provided, a roller 8 which presses the arm 2 is mounted at one end of the arm 7, and the other end of the arm 7 is coupled to a Bowden cable 4 connected to a body 10 side. When the cable is lifted, the arm 7 is rotated counterclockwise at the fulcrum 9 as a center. Thus, the roller 8 presses the arm 2, and a current collecting shoe 1 is isolated from a current feeding rail 5. In this manner, the weight of the movable part of the current collector can be largely reduced. |
