PROBLEM TO BE SOLVED: To provide a dynamic damper preventing a mass body from slipping off, even if an elastic connecting part is broken. SOLUTION: In the dynamic damper, a support fitting 14 supporting the mass body 12 includes a fixed plate part 34 facing a back face 24 of the mass body and a pair of right and left support arm parts 36, 38 erected from right and left side edges 34A of the fixed plate part and respectively opposed to right and left side faces 26, 28 of the mass body, and elastic connecting parts 16 are interposed between right and left side faces of the mass body and the pair of support arm parts. In a pair of right and left first slipping off restriction wall parts 44, 46, tip parts of a pair of support arm parts 36, 38 are respectively bent inward on a front 22 side of the mass body 12 to restrict slipping off of the mass body on the front side. A second slipping off restriction wall part 48 is provided to be erected from a lower edge of the fixed plate part 34 and be opposed to a lower face of the mass body 12 and thereby to restrict downward slipping-off of the mass body.
