PROBLEM TO BE SOLVED: To prevent deterioration of a damper rubber by heat of an engine while preventing deformation of the damper rubber provided on a crank pulley. SOLUTION: In this crank pulley 19 for an engine, an outer circumferential surface of a hub part 35 fixed to an axial end of a crankshaft 18 protruded from a chain cover 38 is connected to an inner circumferential surface of a circular pulley main body part 36 around which a belt 26 is wound through a circular damper part 37 provided with damper rubbers 42 and 43 capable of absorbing vibration of the crankshaft 18. A stopper member 44 is provided on a side surface on the opposite side of the damper part 37 to the chain cover 38 to restrict excessive deformation of the damper rubber 43, so that a vibration absorbing function and a driving force transmitting function can be securely achieved. Since a stopper member 44 covers only a part of the damper rubber 43, heat radiation is not prohibited, thereby deterioration of the damper rubber 43 by temperature rise is prevented.
