The lever (and its fulcrum). Humans have used simple levers and fulcrums in prehistory for prying and lifting — long before the wheel was invented. The wheel appears around 3500 BCE in Mesopotamia; springs as manufactured mechanical components came much later (although elastic devices like bows are also very old).
