It is a device that can store elastic energy. It is not a machine, which changes force and distance and/or direction.
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
Simple
Pulley can prove that simple machine changes the direction of effort.
by increasing the distance.

Levers, inclined planes, and compound pulleys all do that.
a simple machine is a mechanical device

The product of force times the distance the force was directed in, is called "work".The relationship between distance and force is that, when using a simple machine, to move an object it requires less force to move an object a farther distance when using a simple machine than moving an object without a simple machine.The relationship between distance and force is that, when using a simple machine, to move an object it requires less force to move an object a farther distance when using a simple machine than moving an object without a simple machine.Addition: "Using a Force (y-axis) over Distance (x-axis), the Work done can be estimated by calculating the area under the graphed line." -Arian.

That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.
Spring is a simple machine. When the driver takes the car in Des spring force to reduce the car's body.
Simple
You multiple a force time the distance over which the force is applied.
