Summary:PROBLEM TO BE SOLVED: To provide a damper pulley having a simple structure and excelling in durability life.SOLUTION: A ball guide surface 16 formed with a plurality of crest parts cyclically axially bulging in a rotation direction is formed on one-side coaxially relatively rotatable rotating body 2 side, a ball holding surface 17 axially facing the ball guide surface 16 is formed on the other-side rotating body 3 side, a plurality of balls 10 are circumferentially arranged and held between the ball guide surface 16 and the ball holding surface 17, ball housing parts 15 for housing the circumferentially-arranged balls 10 by regulating movement in the rotation direction are formed on the rotating body 3 on the side formed with the ball holding surface 17, a ball holding plate 11 of a separate member formed with the ball holding surface 17 is made movable in the axial direction of the rotating body 3, and a compression coil spring 12 for pressing the ball holding plate 11 to the ball 10 side is arranged, whereby this damper pulley having a simple structure and excelling in durability life can be provided.
