ABSTRACT:
A power transmission mechanism which is adapted to completely interrupt power transmission when a torque exceeds a predetermined value, and which has a simple configuration and is manufactured at low cost, and which is bidirectionally rotatable. When a torque, whose magnitude is not more than the predetermined value, is transmitted from a pulley (1) to a shaft (4), each of three elastic members is accommodated in such a manner as to extend over both of a holding portion (3) of the pulley and a holding part (6) of a hub (5). When an excessive torque, whose magnitude exceeds the predetermined value, is applied to the pulley, deformation of each of the elastic members is gradually enhanced by a compressive force applied from the pulley in a radial direction, so that each of the elastic members moves in the radial direction. Then, each of the elastic members further advances and is detached from a corresponding one of the holding portion of the pulley. Subsequently, each of the elastic members passes through a restriction portion 8 provided in a corresponding one of the holding part of the hub. Finally, each of the elastic members is accommodated in an inner portion (9) of the corresponding one of the holding part. Consequently, the transmission of the torque from the pulley to the hub is completely interrupted.
