摘要：A propeller for a boat includes a propeller shaft(20) having a shaft hole, a shaftsleeve(30) mounted in the shaft hole(26) of the propeller shaft and provided with a metalcore(32) with a through hole for insertion of a driving shaft of the boat, and a shock-absorbing member(34) covering an outer surface of the metal and having an outer
surface contacted with an inner surface of the propeller shaft that surrounds the shafthole(26); and a lock unit(40) mounted on the driving shaft for fixing the driving shaft inthe through hole of the shaft sleeve(30), so that the propeller is rotatable by the drivingshaft. When the propeller bumps hard things during rotation to result in vibration to thepropeller, the shock-absorbing member can absorb the vibration so as to protect thedriving shaft from damage.
