Claims

[Scope of utility model registration request]

An inertial body consisting of a drive plate connected to the drive shaft, a flywheel coaxially provided with the drive plate and rotatable relative to the drive plate, and between the drive plate and the flywheel. In the torque fluctuation absorbing device equipped with an interposed spring mechanism, the spring mechanism includes a coil spring and spring seats provided at both ends of the coil spring, and the spring mechanism includes a coil spring and a spring seat provided at both ends of the coil spring, and A torque fluctuation absorbing device, characterized in that the member is provided with a circumferential long groove that accommodates the coil spring and supports the circumferential force exerted by the coil spring due to the relative rotation.
