A pawl is a small metal catch or lever that fits into the teeth of a gear or wheel and stops it from turning backward. It lets motion go one way but blocks it in the opposite direction, like the click you hear when you use a ratchet.
In everyday life, you’ll meet pawls in bike freewheels, hand-crank winches, and old-fashioned watches. When you pedal a bike and coast without the pedals moving, the pawl inside the rear hub keeps the wheel spinning while the gears stay still. Mechanics call it “the clicky bit,” and campers know it as the tiny part that keeps a tent-tightening ratchet from slipping back.
Meaning & Usage Examples
• Bike freewheel: Pawls let the wheel roll while the pedals rest.
• Car jack: Pawls lock the lift in place so the car doesn’t drop.
• Fishing reel: Pawls stop the spool from unwinding when a fish pulls.
Context / Common Use
DIYers and repair videos often mention pawls when fixing garden hose reels, wind-up clocks, or winches. If you open the side panel and hear a gentle click as you turn the gear, you’re listening to the pawls doing their job.
What does a pawl do?
