PROBLEM TO BE SOLVED: To provide a dynamic damper capable of independently attenuating two types of vibration of high frequency and low frequency generated on a pipe member such as a drive shaft for a vehicle. SOLUTION: The dynamic damper 10 is provided with a disk shape attachment metal fitting 11 press-fitted in the drive shaft 1 and fixed to the drive shaft 1 in a condition vertical to an axial direction, a rod shaped center axis metal fitting 13 fixed on center on one surface side (left surface in a figure) of the attachment fitting 11 and vertically extending, a cylindrical mass metal fitting 14 coaxially arranged outward in radial direction of the center axis metal fitting 13 with keeping interval from the center axis metal fitting 13 and an attachment metal fitting11, a rubber elastic body 16 elastically connecting the attachment fitting 11, the center axis metal fitting 13 and the mass metal fitting 14, and a pair of recessed parts 18 extending in an axial direction on both sides of the center axis metal fitting 13 of the rubber elastic body 16 in radial direction.
