An exterior lever lock device with a clutch assembly is mounted on a door, is connected to a bolt and an indoor lever lock device and has a lever assembly, a driving assembly, a clutch assembly and a driven assembly. The driven assembly has an inner sleeve and a locking panel fastened to the clutch assembly and selectively engaging the inner sleeve.

An endurance of the exterior lever lock device is prolonged for improved lock performance.
