Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pantograph that is improved so as to make it possible to put a contact force between the pantograph and a trolley wire into a proper range by minimizing the change of an average value of lift even if the elevation angle of a shoe changes. SOLUTION: The pantograph 1 comprises the shoe 22 pushed against the trolley wire 1 via a slider 22a and a frame portion 24 which supports the shoe. As the elevation angle of the shoe 22 changes while traveling, an average value of the lift which acts on the shoe 22 changes. To reduce the amount of change of this lift, porous members 26a, 26b having continuous air holes (which means that air holes are continuously connected to each other) are provided on the front and rear surfaces of the shoe 22.
