Abstract
A torque limiting mechanism includes an axial space formed in a cylindrical wall of a pulley, and a pin protruding and extending from a back surface of a discharge disc. The pin is inserted into the axial space, and a rubber damper is installed between the inner surface of the axial space and the pin. When torque difference between the pulley and the discharge disc exceeds a threshold, a root portion of the pin is broken to separate the discharge disc from the pulley, thereby interrupting rotation transmission from the pulley to the discharge disc.
