Abstract
A power transmission apparatus comprises a pulley mounted rotatably on a casing of a rotary device, a hub coupled to the pulley by fitting between depressions and protrusions, a power shutoff member for preventing excessive torque between a rotary shaft and the hub, and an engaging device for engaging the hub and the pulley each other. The engaging device includes a first stepped portion formed radially on the outer periphery of the hub and a second stepped portion formed radially on the inner peripheral wall of a rim of the pulley in such a manner as to engage the first stepped portion in the axial direction.
