Patent ID: 7025680

Claim:
A torque transmission device, which transmits torque from a drive source to a rotating device, the torque transmission device comprising: a first rotator, which receives the torque transmitted from the drive source and is rotated by the torque; a second rotator, which is connected to a rotatable element of the rotating device and is rotated integrally with the rotatable element; a torque limiter, which is arranged in a torque transmission path between the first rotator and the second rotator, wherein the torque limiter transmits torque, which is transmitted from the drive source to the first rotator, to the second rotator, and wherein the torque limiter disables the transmission of the torque from the first rotator to the second rotator when the transmitted torque, which is transmitted from the first rotator to the torque limiter, becomes equal to or greater than a predetermined value; and a weight member, which is secured to the second rotator and serves as an inertia mass, which generates inertia that limits torque fluctuations of the rotating device, wherein the weight member is secured to the second rotator at a point that is radially inward of the torque limiter, and an outer peripheral edge of the weight member is located radially outward of the torque limiter.
