PURPOSE: To absorb the vibration induced on the contact plane between the collector shoe and a contact wire by constituting the collecter shoe by a resilient conducting material.
CONSTITUTION: A shoe plate 3 is provided on a pantograph collector frame 6 via a collector shoe support 5 and a restoring spring 4. A base plate 8 is fixed on the upper surface of the shoe plate 3. At both ends of the base plate 8, the collector shoe main body 7 is fixed and tightened by a tightening bolt 11 together with a keep plate 10 via a rubber plate 9. The shoe main body 7 is formed by a combined body of resilient thin wires of a conductive material, and the entire body 7 is provided with elasticity. A gap 12 is provided between the shoe main body 7 and the base plate 8, so that the shoe main body 7 does not contact with the base plate 8 when the contact pressure is applied on the shoe surface 7'. In this constitution, the vibration induced on the contact surface between the shoe and the contact wire can be absorbed.
