Claims

[Scope of utility model registration request]

An inertial body is composed of a drive plate connected to the drive shaft, and a flywheel coaxially provided with the drive plate so as to be able to rotate relative to the drive plate, and between the drive plate and the flywheel. In the torque fluctuation absorbing device, a spring mechanism is interposed to transmit the rotation of the drive shaft to the flywheel via the drive plate and the spring mechanism, wherein the spring mechanism is arranged in a circumferential direction of the inertial body. It consists of a spring arranged facing toward the spring and a pair of spring seats provided at both ends of the spring. A torque fluctuation absorbing device, characterized in that a stopper portion for suppressing contraction of the spring is provided integrally with the spring seat.
