Coil spring

（重定向自Helical Spring）

Oxy-cut spring showing deformation due to loss of tempering in adjacent turn

A coil spring, also known as a helical spring, is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded.
