Abstract: Provided is a vibration damping device including guide surfaces that are concave surfaces formed in a support member so as to curve toward the outer periphery of the support member; mass bodies that, as the support member rotates, roll on the guide surfaces while being pressed against the guide surfaces by a centrifugal force; and inertia rings that are rotatably coupled to the mass bodies and swing about the center of rotation of the support member. When the vibration damping device is in equilibrium, the center of gravity of each mass body is located radially outward of the joint position between the mass body and the inertia rings. As the support member rotates, the inertia rings swing relative to the support member about the center of rotation of the support member, and the mass bodies roll on the guide surfaces.

Abstract: First to fourth springs SP11 to SP22, two each of four types of springs, are disposed such that attachment radii r11 to r22, which are the distances from a central axis CA of a damper device to the axes of the respective first to fourth springs SP11 to SP22, are equal. Further, the first to fourth springs SP11 to SP22 are disposed such that the axes thereof are arranged in the same plane. With this arrangement, the four types of springs (first to fourth springs SP11 to SP22) can be compactly arranged, and the axial length of the damper device can be reduced.
