How to say "lever" in Japanese

• レバーCommon
  nounCovers mechanical levers, especially control levers and handles on machines, vehicles, and equipment. This is the everyday word when you pull, push, or flip a lever on some device.
  レバーを押おしあげて下ください。↗

  Please push up the lever.
• てこ
  nounRefers to the simple rigid bar used with a fulcrum to lift or move things, and by extension figurative leverage. Less common than レバー, and usually written in kana alone.
  ねじ、てこ、くさび、滑車かっしゃなどは単一たんいつ機械きかいと呼よばれる。↗

  The screw, the lever, the wedge, the pulley, etc. are called simple machines.

Use 「レバー」 for the machine part or control handle; use 「てこ」 for the simple bar/pivot tool, including figurative leverage — both gloss 'lever', but 「てこ」 is less common.
