Disclosed is a finger rehabilitation exercise guide apparatus, which is driven through a linear actuator to have a compact layout in an outer surface direction from an operation direction and is configured in such a way that a position of a prismatic joint in an inner surface layout of the operation direction is changeable by a designer, and as necessary, one prismatic joint, one revolute joint, and a link having opposite ends connected with a corresponding prismatic joint and revolute joint are replaced with one pin-in-slot joint while freely changing the position of the prismatic joint, to realize a small number of components and to precisely guide movement of the wearer's finger.
