Abstract
A power transmitting mechanism transmits power from an engine to a drive shaft of a compressor. A pulley is supported by the compressor and is coupled to the engine. A hub is attached to the drive shaft. Rollers are located on the pulley. Elastic transmission arms are located between the pulley and the hub. The distal end of each arm is curved, and the proximal end is coupled to the hub. When the rollers are engaged with the arms, power is transmitted between the pulley and the hub. When, due to excessive torque, the rollers escape from the corresponding arm, power transmission between the pulley and the hub is disconnected. The distal ends of the arms are movable in the radial direction. When the rollers disengage from the corresponding arms, the distal ends of the arms move radially such that the pulley and the hub relatively rotate without interference by the arms.
