Abstract
A torsional damper includes a torque limiter and a damper. The torque limiter includes at least two friction members, allows transmission of torque, and prohibits transmission of excessive torque. The damper absorbs torsional vibration through resilient deformation of a spring. The torque limiter is a wet torque limiter in which the friction members are arranged in an oil chamber filled with lubricating oil. The damper is a dry damper in which the spring is not immersed in the lubricating oil.
