Abstract: A movable finger for prostheses, having a base a first intermediate portion connected to the base, a second intermediate portion connected to the first intermediate portion, and a fingertip connected to the second intermediate portion. The prosthesis further includes a first intermediate portion bending mechanism for actuating an actuator disposed in the base to pull a first wire to turn an eccentric member, a second intermediate portion bending mechanism for pulling a second wire wound around a pulley disposed as a movable pulley in the first intermediate portion by the eccentric member, whereby the pulling and bending of the second intermediate portion is by a third wire connected to the pulley, and a fingertip bending mechanism for pulling and bending the fingertip by a fourth wire connected to the first intermediate portion, whereby the pulling and straightening is by a fifth wire.
