What is a Zippo cam spring?

For those of you who are not familiar with Zippo, a cam spring is a plate spring part that holds down the cam.

Please take a look at this image.

The cam spring is the plate shaped part attached to the protruding part of the wick by the gold colored clasp.

To understand the role of this part, try to raise or lower the cam without closing the lid.

You will see that the cam spring holds the cam in place from below, causing the cam to click and move with great energy.

The Zippo lid is supported by the cam spring via the cam. It is thanks to the cam spring that the Zippo’s lid opens and closes with a jerk and a snap.

The cam spring loses its springing ability if the Zippo is opened and closed too many times.

It is one of the parts that should be replaced and maintained when the movement of the lid loses its springiness, or when the lid is half-open when it is turned upside down.
