A dynamic damper, wherein flat surfaces approximately orthogonal to the axis of a drive shaft and facing each other are formed on the side walls of mass parts adjacent to each other. Where distances along the axial direction of the drive shaft between center points C bisecting the lateral dimensions D of the connection support parts and the gravity centers G of weights are A and the lateral dimensions of the mass parts having the weights and positioned parallel with the axis of the drive shaft are B, the distances A and the lateral dimensions B are set to fulfill the requirement of the relational expression A<=(B/3). |
