Abstract
A device for transmitting rotational power from an automobile engine to a compressor for use in an automobile air conditioning system is provided. The device includes a pulley, which is supported on a housing of the compressor for rotation, for receiving rotational power from the automobile engine, and a hub connected to the drive shaft. At least one elastic member which defines outer and inner peripheral surfaces is provided. A first holder member is provided along the outer periphery of the hub for holding the elastic member. A second holder member, which is connected to the pulley, is provided for holding the elastic member. The first and second holder members radially cooperate with each other to circumferentially hold the elastic member during normal operation to transmit the rotation. The first and second holder members are disconnected by deformation of the at least one elastic member when a relative rotation between the pulley and drive shaft occurs. The connecting member and the first holder member define a relief clearance therebetween for facilitating the deformation of the at least one connecting member.
