Claims

[Scope of utility model registration request]

a first mass connected to a drive shaft; a second mass disposed coaxially with the first mass so as to be relatively rotatable; and a second mass attached to the first mass side on a predetermined circumference. a sub-plate having a plurality of windows and a stopper part provided at one end of each window part in the rotation direction; and a stopper part attached to the second mass side and facing the sub-plate in the rotation direction. A flywheel is constituted by the provided hub plate, and a spring mechanism having a coil spring having spring seats at both ends that abut the stopper portions, respectively, is connected to the stopper portion of the sub-plate and the hub plate. The fluctuation absorbing device is interposed between the stopper portion of the sub-plate, and the stopper portion of the sub-plate is provided with a contact receiving surface facing in the direction of rotation, and the spring seat is provided with a contact receiving surface that is mutually flush with the contact receiving surface. A regulating means is provided between the sub-plate and the spring seat, and includes a concave portion and a convex portion that are engaged with each other to regulate movement of the spring seat in the radial direction. A torque fluctuation absorbing device characterized by:
