Torque transmission device having torque limiter

摘要

A torque transmission device includes a pulley, a cylindrical member, a torque limiter and a weight member. The pulley is rotated by torque transmitted from a drive source. The cylindrical member is connected to a rotatable shaft of a compressor and is rotated integrally with the rotatable shaft. The torque limiter is arranged between the pulley and the cylindrical member and transmits the torque from the pulley to the cylindrical member. The torque limiter disables the transmission of the torque when the torque becomes equal to or greater than a predetermined value. The weight member is secured to the cylindrical member at a point closer to the rotatable shaft than the torque limiter.
