Zusammenfassung:	PURPOSE:To manufacture a sintered alloy for a pantagraph excellent in wear resistance and sliding properties by mixing specified amounts of Cr powder, metallic sulfide P and a stearic acid series lubricant into iron powder, compacting and sintering the mixed powder and thereafter impregnating Pb or a Pb alloy into the sintered body. CONSTITUTION:A sliding plate for a pantagraph for current collecting used in a high speed electric car is manufactured by a sintered alloy. For this purpose, by weight, 25 to 33% Cr powder, 3 to 9% powder of a solid lubricant such as MoS2 and WS2,
