PROBLEM TO BE SOLVED: To achieve a wider range of selecting a vehicle layout by increasing a degree of freedom in arranging mechanisms and equipment on a vehicle. SOLUTION: This dynamic damper 22 comprises a body 24, two mass parts 26a, 26b oriented and protruded outside a driving shaft 12 in the direction of its diameter, and connection supporting parts 28a, 28b narrower than the mass parts 26a, 26b for connecting the body 24 to the mass parts 26a, 26b, respectively. Weights 36a, 36b are stored in the mass parts 26a, 26b, respectively. The weights 36a, 36b are formed of powder of tungsten alloy such as W-1.8Ni-1.2Cu, W-3.0Ni-2.0Cu, W-5.0Ni-2.0Fe, or W-3.5Ni-1.5Fe or of a sintered body formed by sintering tungsten powder via metal binder.
