- Linkage: Connects the crank and rocker to drive each other's motion; it is referred to as a linkage.
- Crank: A linkage that can rotate 360° around a fixed axis; it is called a crank.
- Rocker: A linkage that performs a swinging motion of a certain angle around a fixed axis; it is known as a rocker."
