PROBLEM TO BE SOLVED: To improve the easiness of press-fitting of a dynamic damper into a hollow shaft and the drawing resistant load characteristic thereof while simplifying the formation of a rubber layer in the dynamic damper having the rubber layer on the outer periphery. SOLUTION: In this dynamic damper 10, an outer pipe 20 includes outwardly extending parts 22 at a plurality of positions spaced in the circumferential direction of the cylinder, respectively. The outer periphery of the rubber layer 50 put on the outer peripheral surface of the outer pipe 20 is circular. The dynamic damper 10 is press-fitted into the circular hole of the hollow shaft 2.
